System Requirements
Requires Perl 5.004 or later. No other libraries or software required.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 should 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 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: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.
Executable Name Operation Print meta information in window and pause before terminating. Generate output " .txt" files with detailed meta information.Generate sidecar " .xmp" files.Add copyright information (and don't pause before terminating).
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.

Verbose and HtmlDump Output
The Verbose (-v) and HtmlDump (-htmlDump) options print additional
information that can be very useful for debugging or when decoding new tags.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
from family 0 or 1 (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: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 exiftoolexiftool -filename -imagesize -exif:fnumber -xmp:all image.jpg
-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:
- Tag names sometimes differ from their descriptions. Use the
-scommand-line option to see the actual tag names instead of the descriptions shown when extracting information. - 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
-foption may be used to force all specified tags to be displayed. - Information for a given tag name may occur in multiple locations within a
single file. By default these duplicate tags are suppressed, but the
-aoption may be used to extract all tags. - 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:In this example, MyShortcut is a shortcut for the CreateDate, ExposureTime and Aperture tags, and MyAlias is a shortcut for FocalLengthIn35mmFormat.
%Image::ExifTool::UserDefined::Shortcuts = ( MyShortcut => ['createdate','exposuretime','aperture'], MyAlias => '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

ExifTool classifies tags into groups in five different families. These groups are:The exiftool output can be organized based on these groups using the

-g or -G option. See the
GetGroup function in the ExifTool library
for a description of the group families.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:Quotes are required around VALUE if it contains spaces or other special characters, and around the whole argument if the '† See the Writer Limitations for some limitations of this feature.
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:]TAG=VALUE Sets value of TAG (only in GROUP if specified) -[GROUP:]TAG+=VALUE Adds item to a list, shifts a date/time, or increments a number -[GROUP:]TAG-=VALUE Removes item from a list, shifts a date/time, or deletes TAG if it has the specified value -[GROUP:]TAG<=FILE Sets tag value from contents of specified file
<='
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) XMPMany 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 or 1 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 and trailers are removed
which effectively removes all metadata, but for other formats the results are less
complete:
- JPEG - APP segments and trailers are removed.
- TIFF - XMP, IPTC and the ExifIFD are removed, but some EXIF may remain in IFD0.
- PNG - Only iTXt, tEXt and zTXt chunks (including XMP) are removed.
- PDF - The original metadata is never actually removed.
- PS - Only some PostScript and XMP may be deleted.
- MOV/MP4 - Only XMP is deleted.
- RAW formats - It is not recommended to remove all metadata from RAW images because this may remove some proprietary information that is necessary for the image to be properly rendered.
Known Problems
- 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.
- 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).
- 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]
- 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]
- 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]
Security Issues
Some ExifTool options (-if, -p, and copying
arguments like "-DSTTAG<STR") have the ability to execute Perl
code from within command-line arguments. This may be a security problem if
ExifTool is executed from another application that blindly passes untrusted file
names on the command line (since they may be interpreted as ExifTool options if
they begin with a dash). To be secure, the calling application must ensure that
input file names do not start with a dash (U+002D) or a Unicode minus sign
(U+2212). The easiest way to accomplish this is to prefix input file names with
a known directory name, eg.) "./FILENAME".Date/Time Shift Feature
Have you ever forgotten to set the date/time on your digital camera before taking a bunch of pictures? ExifTool has a time shift feature that makes it easy to apply a batch fix to the timestamps of the images (eg. change the "Date Picture Taken" reported by Windows Explorer). Say for example that your camera clock was reset to 2000:01:01 00:00:00 when you put in a new battery at 2005:11:03 10:48:00. Then all of the pictures you took subsequently have timestamps that are wrong by 5 years, 10 months, 2 days, 10 hours and 48 minutes. To fix this, put all of the images in the same directory ("DIR") and run exiftool:The example above changes only the DateTimeOriginal tag, but any writable date or time tag can be shifted, and multiple tags may be written with a single command line. Commonly, in JPEG images, the DateTimeOriginal, CreateDate and ModifyDate values must all be changed. For convenience, a shortcut tag called AllDates has been defined to represent these three tags. So, for example, if you forgot to set your camera clock back 1 hour at the end of daylight savings time in the fall, you can fix the images with:exiftool "-DateTimeOriginal+=5:10:2 10:48:0" DIR
See Image::ExifTool::Shift.pl (download in PDF format) for details about the syntax of the time shift string.exiftool -AllDates-=1 DIR
Renaming and/or Moving Files
By writing a new value to the FileName and/or Directory tags, files can be renamed and/or moved to different directories. This can be a very powerful tool in combination with the-d (date format) option for
organizing images by date/time. For example, the following command renames all
images in directory "DIR" according to the individual file's
creation date in the form "YYYYmmdd_HHMMSS.ext".Or a new directory can be specified by setting the value of the Directory tag. For example, the following command moves all images originally in directory "exiftool "-FileName<CreateDate" -d "%Y%m%d_%H%M%S.%%e" DIR
DIR" into a directory hierarchy organized by
year/month/day:Read here for more details about this powerful feature.exiftool "-Directory<DateTimeOriginal" -d "%Y/%m/%d" DIR
Improving Performance
There is a significant overhead in loading ExifTool, so performance may be greatly improved by taking advantage of ExifTool's batch processing capabilities (the ability to process multiple files or entire directories with a single command) to reduce the number of executed commands when performing complex operations or processing multiple files.† [One exiftool user documented a 60x speed increase by processing a large number of files with a single command instead of running exiftool separately on each file.] Also, the-execute option may be used to perform multiple independent
operations with a single invocation of exiftool, and together with the
-stay_open option provides a method for calling applications to
avoid this startup overhead.The processing speed of ExifTool can be improved when extracting information by reducing the amount of work that it must do. Decrease the number of extracted tags by specifying them individually (
-TAG) or by group
(-GROUP:all), and disable the composite tags (-e) and
the print conversions (-n) if these features aren't required. Note
that the exclude options (-x or --TAG) are not very
efficient, and may have a negative impact on performance if a large number of
tags are excluded individually.The
-fast option can significantly increase speed when
extracting information from JPEG images which are piped across a slow network
connection. However, with this option any information in a JPEG trailer is not
extracted. For more substantial speed benefits, -fast2 may be
used to also avoid extracting MakerNote information if this is not required.When writing, avoid copying tags (with
-tagsFromFile) or using
the -if or -fileOrder option because these will add
the extra step of extracting tags from the file. Without these the write
operation is accomplished with a single pass of each file.
† However,
note that when the -csv option is used, information from all files
is buffered in memory before the CSV output is written. This may be very memory
intensive and result in poor performance when reading a large number of files in
a single command.
The Image::ExifTool Perl Library Module
The "exiftool" script provides a command-line interface to the
Image::ExifTool Perl library module which is part of the ExifTool distribution.
The Image::ExifTool module can be used in any Perl script to provide easy access
to meta information. Here is an example of a very simple script that uses
Image::ExifTool to print out all recognized meta information in a file: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.

Boldly Go where No Man has Gone Before...
There is still much unknown information in the maker notes for many camera models. (To see this information, run exiftool with the-U
option.) 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. If you manage to figure out what any of it means, send me an
e-mail (phil at owl.phy.queensu.ca) and I'll add your new discoveries to
ExifTool. Many thanks to all who have helped so far...Acknowledgements
