https://exiftool.org/ ExifTool by Phil Harvey Read, Write and Edit Meta Information! Also available --> Utility to fix Nikon NEF images corrupted by Nikon software Note: If exiftool.org goes down, it is because of the crappy DreamHost web hosting which disables an "unlimited traffic" web site if a single bot hammers the site with a moderate load.

ExifTool supports many different metadata formats including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, Lyrics3, as well as the maker notes of many digital cameras by Canon, Casio, DJI, FLIR, FujiFilm, GE, GoPro, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Motorola, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/ Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony. ExifTool is also available as a stand-alone Windows executable and a MacOS package: (Note that these versions contain the executable only, and do not include the HTML documentation or other files of the full distribution above.) Windows Executable: exiftool-12.54.zip (6.6 MB) The stand-alone Windows executable does not require Perl. Just download and un-zip the archive then double-click on "exiftool (-k).exe" to read the application documentation, drag-and-drop files and folders to view meta information, or rename to "exiftool.exe" for command-line use. Runs on all versions of Windows. (Note: Oliver Betz provides an alternate ExifTool Windows installer that avoids some problems of the self-extracting archive version above. Please post here if you have any problems/comments with this version.) MacOS Package: ExifTool-12.54.dmg (3.2 MB) The MacOS package installs the ExifTool command-line application and libraries in /usr/local/bin. After installing, type "exiftool" in a Terminal window to run exiftool and read the application documentation. Read the installation instructions for help installing ExifTool on Windows, MacOS and Unix systems. * Click here for the SHA1 and MD5 checksums to verify these distribution packages. * The version number of the latest ExifTool release may be found here.

Read about the -ext, -if, -p and -tagsFromFile options in the application documentation. (This is common mistake number 3.) What People are Saying about ExifTool "In my experience, nothing but nothing is as complete, powerful, and flexible as Phil Harvey's exiftool ... I've never seen anything that's in the same ballpark for power." - dpreview forum "While there are a lot of image tools available, nothing comes close for accessing/updating the metadata like ExifTool" - merg's blog "Fast, reliable and amazingly comprehensive ..." - CPAN ratings "... the one piece of free software that gets the most detailed exif data of /any/ tool I've found." - gnome mail archives "ExifTool makes every other EXIF reader (and writer) than I've seen, including the camera manufacturers' readers, look lame." - photo.net Nikon forum "Insanely great tool with a long learning curve ..." - Adobe Forums "ExifTool has been outstanding in our custom used Tesla image gallery build. We are able to aggregate image meta from our user base and incorporate this into development iterations to continually optimize our platform..." - Find My Electric "... it's super awesome, it's super reliable and after many years of development it's still being updated!" - P_W999 blog "... it is the mother of all EXIF utilities; the BFG of meta-data extraction; the Pan Galactic Gargle Blaster of EXIF tools ... This thing will suck the last bit of metadata out of whatever image file you throw at it!" - Open Photography Forums "... it is total fucking gibberish to me." - Reddit Linux Questions Supported File Types ExifTool can Read, Write and/or Create files in the following formats. Also listed are the support levels for EXIF, IPTC (IIM), XMP, ICC_Profile and other metadata types for each file format.

System Requirements Requires Perl 5.004 or later. No other libraries or software required, but some optional Perl modules may be added to enable certain ExifTool features (for details, see the DEPENDENCIES section of the README file included in the full distribution). Windows users: A stand-alone Windows executable version of ExifTool is available which doesn't require Perl. You can also use the pure Perl version if you already have Perl installed. (You can get a good, free Perl interpreter from activeperl.com.) Everyone else (Mac, Unix, etc): Don't worry, you already have Perl installed. Running ExifTool The exiftool application provides a convenient command-line interface for the Image::ExifTool Perl package (both included in the full distribution). Once you have downloaded and extracted the distribution, you can immediately run exiftool (without building or installing) by typing "DIR/exiftool FILE" (or "perl DIR/exiftool FILE " in Windows), where DIR is the exiftool directory and FILE is the name of an image file, including directory name. Read the installation instructions or the README file included in the full distribution for help installing ExifTool. Many command-line options are available to allow you to access a wide range of features. Run exiftool with no arguments for a complete list of available options with examples. Running in Windows i) From the command line: The Perl application ("exiftool") is run by typing "perl exiftool". Alternately, you may be able to rename it to "exiftool.pl" and type "exiftool.pl", but this requires that the proper Windows associations have been made for the ".pl" extension. The stand-alone version ("exiftool(-k).exe") should be renamed to "exiftool.exe" to allow it to be run by typing "exiftool" at the command line. If the exiftool executable ("exiftool.pl" or "exiftool.exe") is not in the current directory or your system PATH, then its directory must be specified on the command line (eg. by typing "c:\path_to_exiftool\ exiftool.pl" or "c:\path_to_exiftool\exiftool"). Note that when typing commands in the "cmd.exe" shell, you should use double quotes instead of single quotes as shown in some examples. ii) Stand-alone version in the Windows GUI: Double-click on "exiftool(-k).exe" to read the application documentation, or drag-and-drop files and folders to run exiftool on the selected files. Simple options may be added inside brackets in the name of the stand-alone executable. (But note that the characters /\?*:|"<> may not be used because they are invalid in Windows file names.) In this way, the behaviour of the drag-and-drop application can be customized. For example: Executable Name Operation exiftool(-k).exe Print meta information in window and pause before terminating. exiftool(-k -a -u -g1 -w txt).exe Generate output ".txt" files with detailed meta information. exiftool(-k -o %d%f.xmp).exe Generate sidecar ".xmp" files. Add copyright information exiftool(-copyright='Phil Harvey').exe (and don't pause before terminating). Hint: Options may also be added to the "Target" property of a Windows shortcut for the executable. Using a shortcut has 3 advantages over adding options in the file name: 1) different shortcuts may be created without requiring multiple copies of the executable, 2) characters which are invalid in file names may be used, and 3) the shortcuts can be given more meaningful (and convenient) file names. As well, it may be useful to increase the window and buffer sizes to display more information: Right-click on the window's title bar then select "Properties" from the menu and change the window layout settings.

Tag Names Explained A tag name is a "handle" that is used to refer to a specific piece of meta information. Tag names are entered on the command line with a leading '-', in the order you want them displayed. Case is not significant. The tag name may be prefixed by a group name (separated by a colon) to identify a specific information type or location. A special tag name of "All" may be used to represent all tags, or all tags in a specified group. For example: exiftool -filename -imagesize -exif:fnumber -xmp:all image.jpg A complete list of ExifTool Tag Names accompanies this documentation. As well, current lists of available tag names and writable tag names may be obtained using the exiftool -list and -listw options. But perhaps the easiest way to determine a tag name is to use the -s option to print the tag names instead of descriptions for all information in a file. It may also be helpful to use the -G option to display the group names, and the -H or -D option to print the numerical tag ID's for reference. Notes: 1. Tag names sometimes differ from their descriptions. Use the -s command-line option to see the actual tag names instead of the descriptions shown when extracting information. 2. When extracting information, tags will not appear in the output unless they exist in the file, even if they are specified on the command line. The -f option may be used to force all specified tags to be displayed (not including tags specified with wildcards or by -GROUP:all). 3. Information for a given tag name may occur in multiple locations within a single file. By default these duplicate tags are suppressed, but the -a option may be used to extract all tags. 4. Tag names may be suffixed by a '#' character to disable the print conversion on a per-tag basis. See the -n option in the application documentation for more information. Shortcut Tags Shortcut tags represent one or more other tags, and are used like any other tag when reading, writing or copying information. ExifTool defines a few shortcut tags in the Image::ExifTool::Shortcuts module, and allows users to define their own shortcuts in a configuration file called ".ExifTool_config" in their home directory or exiftool application directory. Here is a simple example that defines two shortcuts: %Image::ExifTool::UserDefined::Shortcuts = ( MyShortcut => ['createdate','exposuretime','aperture'], MyAlias => 'FocalLengthIn35mmFormat', ); In this example, MyShortcut is a shortcut for the CreateDate, ExposureTime and Aperture tags, and MyAlias is a shortcut for FocalLengthIn35mmFormat. The current shortcuts may be listed with the -list option. The ~/.ExifTool_config file may also be used to define new tags. For more information about the configuration file, see the sample configuration file included with the ExifTool distribution. Windows tip: You may have difficulty generating a filename beginning with a '.' in the Windows GUI, but it can be done with the "rename" command at the cmd.exe prompt. Tag Groups ExifTool classifies tags into groups in various families. Here is a list of the group names in each family: Family Group Names AFCP, AIFF, APE, APP0, APP1, APP11, APP12, APP13, APP14, APP15, APP3, APP4, APP5, APP6, APP8, ASF, Audible, CanonVRD, Composite, DICOM, DNG, DV, DjVu, Ducky, EXE, EXIF, ExifTool, FITS, FLAC, FLIR, File, Flash, FlashPix, Font, FotoStation, GIF, GIMP, GeoTiff, GoPro, H264, HTML, ICC_Profile, ID3, IPTC, ISO, ITC, JFIF, JPEG, JSON, JUMBF, 0 Jpeg2000, LNK, Leaf, Lytro, M2TS, MIE, MIFF, (Information Type) MISB, MNG, MOI, MPC, MPEG, MPF, MXF, MakerNotes, Matroska, Meta, Ogg, OpenEXR, Opus, PDF, PICT, PLIST, PNG, PSP, Palm, Parrot, PanasonicRaw, PhotoCD, PhotoMechanic, Photoshop, PostScript, PrintIM, QuickTime, RAF, RIFF, RSRC, RTF, Radiance, Rawzor, Real, Red, SVG, SigmaRaw, Stim, Theora, Torrent, Trailer, UserParam, VCard, Vorbis, WTV, XML, XMP, ZIP AC3, AFCP, AIFF, APE, ASF, AVI1, Adobe, AdobeCM, AdobeDNG, Apple, Audible, CBOR, CIFF, CameraIFD, Canon, CanonCustom, CanonDR4, CanonRaw, CanonVRD, Casio, Chapter #, Composite, DICOM, DJI, DNG, DV, DjVu, DjVu-Meta, Ducky, EPPIM, EXE, EXIF, ExifIFD, ExifTool, FITS, FLAC, FLIR, File, Flash, FlashPix, Font, FotoStation, FujiFilm, FujiIFD, GE, GIF, GIMP, GPS, GSpherical, GeoTiff, GlobParamIFD, GoPro, GraphConv, H264, HP, HTC, HTML, HTML-dc, HTML-ncc, HTML-office, HTML-prod, HTML-vw96, HTTP-equiv, ICC-chrm, ICC-clrt, ICC-header, ICC-meas, ICC-meta, ICC-view, ICC_Profile, ICC_Profile#, ID3, ID3v1, ID3v1_Enh, ID3v2_2, ID3v2_3, ID3v2_4, IFD0, IFD1, IPTC, IPTC#, ISO, ITC, Insta360, InteropIFD, ItemList, JFIF, JFXX, JPEG, JPEG-HDR, JPS, JSON, JUMBF, JVC, Jpeg2000, KDC_IFD, Keys, Kodak, KodakBordersIFD, KodakEffectsIFD, KodakIFD, KyoceraRaw, LNK, Leaf, LeafSubIFD, Leica, Lyrics3, Lytro, M2TS, MAC, MIE-Audio, MIE-Camera, MIE-Canon, MIE-Doc, MIE-Extender, MIE-Flash, MIE-GPS, MIE-Geo, MIE-Image, MIE-Lens, MIE-Main, MIE-MakerNotes, MIE-Meta, MIE-Orient, MIE-Preview, MIE-Thumbnail, MIE-UTM, MIE-Unknown, MIE-Video, MIFF, MISB, MNG, MOBI, MOI, MPC, MPEG, MPF0, MPImage, MS-DOC, MXF, MacOS, MakerNotes, MakerUnknown, Matroska, MediaJukebox, Meta, MetaIFD, Microsoft, Minolta, MinoltaRaw, Motorola, NITF, Nikon, NikonCapture, NikonCustom, NikonScan, NikonSettings, NineEdits, 1 Nintendo, Ocad, Ogg, Olympus, OpenEXR, Opus, (Specific Location) PDF, PICT, PNG, PNG-pHYs, PSP, Palm, Panasonic, PanasonicRaw, Parrot, Pentax, PhaseOne, PhotoCD, PhotoMechanic, Photoshop, PictureInfo, PostScript, PreviewIFD, PrintIM, ProfileIFD, Qualcomm, QuickTime, RAF, RAF2, RIFF, RMETA, RSRC, RTF, Radiance, Rawzor, Real, Real-CONT, Real-MDPR, Real-PROP, Real-RA3, Real-RA4, Real-RA5, Real-RJMD, Reconyx, Red, Ricoh, SPIFF, SR2, SR2DataIFD, SR2SubIFD, SRF#, SVG, Samsung, Sanyo, Scalado, Sigma, SigmaRaw, Sony, SonyIDC, Stim, SubIFD, System, Theora, Torrent, Track #, UserData, VCalendar, VCard, Version0, Vorbis, WTV, XML, XMP, XMP-DICOM, XMP-Device, XMP-GAudio, XMP-GCamera, XMP-GCreations, XMP-GDepth, XMP-GFocus, XMP-GImage, XMP-GPano, XMP-GSpherical, XMP-LImage, XMP-MP, XMP-MP1, XMP-PixelLive, XMP-aas, XMP-acdsee, XMP-album, XMP-apple-fi, XMP-ast, XMP-aux, XMP-cc, XMP-cell, XMP-crd, XMP-creatorAtom, XMP-crs, XMP-dc, XMP-dex, XMP-digiKam, XMP-drone-dji, XMP-dwc, XMP-exif, XMP-exifEX, XMP-expressionmedia, XMP-extensis, XMP-fpv, XMP-getty, XMP-hdr, XMP-ics, XMP-iptcCore, XMP-iptcExt, XMP-lr, XMP-mediapro, XMP-microsoft, XMP-mwg-coll, XMP-mwg-kw, XMP-mwg-rs, XMP-nine, XMP-pdf, XMP-pdfx, XMP-photomech, XMP-photoshop, XMP-plus, XMP-pmi, XMP-prism, XMP-prl, XMP-prm, XMP-pur, XMP-rdf, XMP-sdc, XMP-swf, XMP-tiff, XMP-x, XMP-xmp, XMP-xmpBJ, XMP-xmpDM, XMP-xmpMM, XMP-xmpNote, XMP-xmpPLUS, XMP-xmpRights, XMP-xmpTPg, ZIP, iTunes Audio, Author, Camera, Device, Document, 2 (Category) ExifTool, Image, Location, Other, Preview, Printing, Time, Unknown, Video 3 (Document Number) Doc#, Main 4 (Instance Number) Copy# 5 (Metadata Path) eg.

Numerical ID's are given in hex with a leading "0x" if the HexTagIDs API option is set, as are 7 (Tag ID) characters in non-numerical ID's which are not valid in a group name. Note that unlike other group names, family 7 group names are case sensitive.) The exiftool output can be organized based on these groups using the -g or -G option (ie. -g1 to see family 1 groups, or -g3:1 to see both family 3 and family 1 group names in the output. See the -g option in the exiftool application documentation for more details, and the GetGroup function in the ExifTool library for a description of the group families. Note that when writing, only family 0, 1, 2 and 7 group names may be used. Writing Meta Information When writing information, ExifTool preserves the original file by adding "_original" to the file name. Be sure to keep a copy of the original, or thoroughly validate the new file before erasing the original. (Read here for some ramblings on the subject of writing meta information.) Syntax Tag values are written rather than being extracted if any tag name ends with a '=' symbol (or if the -tagsFromFile or -geotag options are used). The '=' may be prefixed by '+', '-' or '<' to add a value, remove a value or set a value from file. The following table outlines the different write syntaxes: Syntax Result -TAG= Deletes all occurrences of TAG -all= Deletes all meta information! ^+ -GROUP:TAG= Deletes TAG only in specified group -GROUP:all= Deletes all information in specified group -[GROUP:] Sets value of TAG (only in GROUP if specified) TAG=VALUE -[GROUP:] Adds item to a list, shifts a date/time, or TAG+=VALUE increments a number -[GROUP:] Removes item from a list, shifts a date/time, or TAG-=VALUE deletes TAG if it has the specified value -[GROUP:] Sets tag value from contents of specified file TAG<=FILE ^+ See the Writer Limitations for some limitations of this feature. Quotes are required around VALUE if it contains spaces or other special characters, and around the whole argument if the '<=' syntax is used (to prevent shell redirection). A special feature allows the print conversion to be disabled on a per-tag basis by suffixing any tag name (including 'all') with the '# ' character. This has the same effect as the -n option, but for a single tag. See the -n option in the application documentation for more details. Note: Changes to PDF files are reversible because the original metadata is never actually deleted from these files. See the PDF Tags documentation for details. Group Priorities ExifTool prioritizes the following types of meta information when writing: 1) EXIF, 2) IPTC, 3) XMP Many tag names are valid for more than one of these groups. If a group name is not specified when writing information, then the information is added only to the highest priority group for which the tag name is valid (however, the information is updated in all groups where the tag already existed). The priority of the groups is given by the list above. Specifically, this means that new information is added preferentially to the EXIF group, or to the IPTC group if no corresponding EXIF tag exists, or finally to the XMP group. Alternatively, information may be written to a specific group only, bypassing these priorities, by providing a group name for the tag. The "Writing Meta Information" section above gave the syntax rules for exiftool command-line arguments to do this. Any family 0, 1, 2 or 7 group name may be used when writing information, although not all groups are writable. The "-tagsFromFile" Option A special ExifTool option allows copying tags from one file to another. The command-line syntax for doing this is "-tagsFromFile SRCFILE". Any tags specified after this option on the command line are extracted from source file and written to the destination file. If no tags are specified, then all writable tags are copied. This option is very simple, yet very powerful. Depending on the formats of the source and destination files, some of tags read may not be valid in the destination file, in which case they aren't written. This option may also be used to transfer information between different tags within a single image or between different images. See the -tagsFromFile option in the application documentation for more details. Writer Limitations * ExifTool will not rewrite a file if it detects a significant problem with the file format. * ExifTool has been tested with a wide range of different images, but since it is not possible to test it with every known image type, there is the possibility that it will corrupt some files. Be sure to keep backups of your files. * Even though ExifTool does some validation of the information written, it is still possible to write illegal values which may cause problems when reading the images with other software. So take care to validate the information you are writing. * ExifTool is not guaranteed to remove metadata completely from a file when attempting to delete all metadata. For JPEG images, all APP segments (except Adobe APP14, which is not removed by default) and trailers are removed which effectively removes all metadata, but for other formats the results are less complete: + JPEG - APP segments (except Adobe APP14) and trailers are removed. + TIFF - XMP, IPTC, ICC_Profile and the ExifIFD are removed, but some EXIF may remain in IFD0. (The CommonIFD0 Shortcut tag is provided to simplify removal of common metadata tags from IFD0.) + PNG - Only XMP, EXIF, ICC_Profile and native PNG textual data chunks are removed. + PDF - The original metadata is never actually removed. + PS - Only XMP and some native PostScript tags may be deleted. + MOV/MP4 - Most top-level metadata is removed. + RAW formats - It is not recommended to remove all metadata from RAW images because this will likely remove some proprietary information that is necessary for proper rendering of the image. Known Problems * [2022-08-23] Sony Imaging Edge Desktop has problems displaying some ExifTool-edited ARW images, although other software (such as Adobe utilites) have no problems with these. * [2020-02-18] Hasselblad Phocus software will no longer update the small preview or thumbnail images of FFF files edited by ExifTool. This is perhaps due to some unreferenced preview information in the file that is lost when edited by ExifTool, but this does not seem to have any other effect. [ExifTool 11.88 and later issue a minor error when attempting to write FFF files, but this problem seems to be fixed in Phocus v3.5.4] * [2019-05-29] Canon Digital Photo Professional 4 (DPP4) will destroy a CR3 image when editing if it had previously been edited by DPP4 followed by ExifTool. [ExifTool 11.45 fixes this by structuring the CR3 to make it safe for editing with DPP4, and may be used to restructure files written by older ExifTool versions.] * [2018-09-27] The Sony Imaging Edge applications give an error when trying to open ARW or ARQ images edited by ExifTool, although other RAW image utilities including Sony IDC (Sony's older RAW image converter), Adobe Photoshop, Lightroom and DNG Converter, Apple Preview, dcraw, Capture One, Affinity Photo, and LibRaw's SonyPixelShift2DNG have no problems with these. * [2016-08-03] Some antivirus software has been known to cause problems for the Windows version of ExifTool. Norton Antivirus may delete ExifTool when it is run, Windows Defender may slow down launching of ExifTool or hang it altogether, and Bitdefender Antivirus may block ExifTool from writing files. Presumably this is due to the way the ExifTool package for Windows works -- it unpacks executable files into a temporary directory and runs from there, which apparently may be seen as a threat by antivirus software. A work-around is to add ExifTool to the exclusion list of the antivirus software. * [2016-05-27] Adobe Camera Raw and DNG Converter 9.5.1 fail to recognize edited Samsung SRW images from some models (NX30, NX300, NX2000 and EK-GN120). [This problem was fixed for the NX models in ExifTool 10.26, and writing of EK-GN120 files was disabled in ExifTool 10.95] * In Windows, ExifTool will not process files with Unicode characters in the file name. This is due to an underlying lack of support for Unicode filenames in the Windows standard C I/O libraries. [This deficiency was addressed in ExifTool 9.79, and ExifTool now supports Windows Unicode file names with some exceptions. See the WINDOWS UNICODE FILE NAMES section of the application documentation for details.] * [2013-11-08] Apple Spotlight and Preview (OS X 10.8.5) and Adobe Photoshop CC (version 14.0) ignore XMP in PNG images if it comes after the image data, which is where ExifTool adds new XMP. This should be considered as a bug in the Apple and Adobe software since XMP is allowed to exist after the image data according to the XMP and PNG specifications. [ExifTool 9.40 provides the PNGEarlyXMP API option to allow writing XMP before the IDAT chunk, but there are caveats associated with its use. ExifTool 11.58 and later remove this option and always write XMP before IDAT, and 11.63 and later write all text chunks before IDAT.] * [2013-04-21] Memory available to ExifTool in the Windows EXE version is limited to a few hundred MB. This limitation has been known to cause unreasonably long processing times (almost 7 minutes) for some large EPS files (> 200 MB) which are processed much faster by the Perl version (< 6 seconds). * [2010-01-12] There is a bug in a number of Adobe utilities which causes some edited Sony ARW images to be displayed with the wrong tone curve. This problem has been observed in Photoshop CS4 Camera Raw 5.6, DNG Converter 5.6 and Lightroom 2.6 with ARW images from the A500, A550, A700, A850 and A900. Other software such as the Sony IDC utility, Apple RAW utilities, dcraw and Capture One have no problems with edited images. [This bug is fixed in Camera Raw 6.3 and LR 3.3] * [2007-07-06] There is a bug in the Apple RAW file support (OS X 10.4.11) which prevents some edited Pentax PEF images from being displayed properly. Other software such as the Pentax Silkypix software and dcraw have no problems with these images. [This bug is fixed in OS X 10.5.4] Security Issues Some ExifTool options (-config, -if, -p, -api filter, -api filterw and copying arguments like "-DSTTAG{$_}\n"; } Note that some tag values may be returned as SCALAR references indicating binary data. The simple script above does not handle this case. See the Image::ExifTool Documentation for more details.

In this area, ExifTool is very much a collaborative effort, and development relies heavily on the input from camera owners to help decode new meta information.
