NAME
exiv2 - Image metadata manipulation tool
SYNOPSIS
exiv2 [options] [action] file ...
DESCRIPTION
exiv2 is a program to read and write Exif, IPTC, XMP metadata and image
comments and can read many vendor makernote tags. The program optionally
converts between Exif tags, XMP properties and IPTC datasets as
recommended by the Exif Standard, the IPTC Standard, the XMP
specification and Metadata Working Group guidelines.
The following image formats are supported:

o Support for GIF, TGA and BMP images is minimal: the image format is
recognized, a MIME type assigned to it and the height and width of the
image are determined.
o Reading other TIFF-like RAW image formats, which are not listed in the
table, may also work.
o Support for BMFF file types such as CR3, HEIF, HEIC, AVIF, and JPEG XL
is a build option. To check if this is enabled, use:
$ exiv2 --version --verbose | grep bmff
enable_bmff=1
o Naked codestream JPEG XL files do not contain Exif, IPTC, or XMP
metadata.
ACTIONS
The action argument is only required if it is not clear from the options
which action is implied.
pr | print
Print image metadata. This is the default action, i.e., the
command exiv2 image.jpg will print a summary of the image Exif
metadata.
ex | extract
Extract metadata to *.exv, XMP sidecar (*.xmp) and thumbnail image
files. Modification commands can be applied on-the-fly.
in | insert
Insert metadata from corresponding *.exv, XMP sidecar (*.xmp) and
thumbnail files. Use option -S .suf to change the suffix of the
input files. Since files of any supported format can be used as
input files, this command can be used to copy the metadata between
files of different formats. Modification commands can be applied
on-the-fly.
rm | delete
Delete image metadata from the files.
ad | adjust
Adjust Exif timestamps by the given time. Requires at least one of
the options -a time, -Y yrs, -O mon or -D day.
mo | modify
Apply commands to modify (add, set, delete) the Exif, IPTC and XMP
metadata of image files. Requires option -c, -m or -M.
mv | rename
Rename files and/or set file timestamps according to the Exif
create timestamp. Uses the value of tag
Exif.Photo.DateTimeOriginal or, if not present,
Exif.Image.DateTime to determine the timestamp. The filename
format can be set with -r fmt, timestamp options are -t and -T.
When no rename format is provided, the default is '%Y%m%d_%H%M%S'
using definitions from strftime(3).
fi | fixiso
Copy the ISO setting from one of the proprietary Nikon or Canon
makernote ISO tags to the regular Exif ISO tag,
Exif.Photo.ISOSpeedRatings. Does not overwrite an existing
standard Exif ISO tag.
fc | fixcom
Fix the character encoding of Exif Unicode user comments. Decodes
the comment using the auto-detected or specified character
encoding and writes it back in UCS-2. Use option -n to specify the
current encoding of the comment if necessary.

OPTIONS
-h Display help and exit.
-V Show the program version and exit.
When -V is combined with -v (Verbose version), build information
is printed to standard output along with a list of shared
libraries which have been loaded into memory. Verbose version is
supported on Windows (MSVC, Cygwin and MinGW builds), macOS and
Linux and is provided for test and debugging.
-v Be verbose during the program run.
-q Silence warnings and error messages from the Exiv2 library during
the program run (quiet). Note that options -v and -q can be used
at the same time.
-Q lvl Set the log-level to 'd'(ebug), 'i'(nfo), 'w'(arning), 'e'(rror)
or 'm'(ute). The default log-level is 'w'. -Qm is equivalent to
-q. All log messages are written to standard error.
-u Show unknown tags (default is to suppress tags which don't have a
name).
-g key Only keys which match the given key (grep).
Multiple -g options can be used to filter info to less keys.
Example: exiv2 -v -V -g webready -g time. The default exiv2
command prints a "summary report" which is quite short. When you
use -g without a -pmod option, you do not get a summary report and
in effect you get -g pattern -pa image ...
$ bin/exiv2 -g Date http://clanmills.com/Stonehenge.jpg
Exif.Image.DateTime Ascii 20 2015:07:16 20:25:28

Xmp.xmp.ModifyDate XmpText 25 2015-07-16T20:25:28+01:00
You may use -pmod filters to further filter output. For example:
$ bin/exiv2 -px -g Date http://clanmills.com/Stonehenge.jpg
Xmp.xmp.ModifyDate XmpText 25 2015-07-16T20:25:28+01:00
The option -g (--grep) applies to keys and not values.
The key may finish with the optional modifier /i to indicate case
insensitive.
-K key Only report data for given key.
Multiple -K options can be used to report more than a single key.
$ exiv2 -K Exif.Photo.DateTimeDigitized -K Exif.Photo.DateTimeOriginal -pt R.jpg
Exif.Photo.DateTimeOriginal Ascii 20 2011:09:18 16:25:48
Exif.Photo.DateTimeDigitized Ascii 20 2011:09:18 16:25:48
-n enc Charset to use to decode Exif Unicode user comments. enc is a name
understood by iconv_open(3), e.g., 'UTF-8'.
-k Preserve file timestamps when updating files (keep). Can be used
with all options which update files. The flag is ignored by read-
only options.
-t Set the file timestamp according to the Exif create timestamp in
addition to renaming the file (overrides -k). This option is only
used with the 'rename' action. See Exif DateTime below for
additional information.
-T Only set the file timestamp according to the Exif create
timestamp, do not rename the file (overrides -k). This option is
only used with the 'rename' action. Note: On Windows you may have
to set the TZ environment variable for this option to work
correctly. See Exif DateTime below for additional information.
-f,-F These options are used by the commands 'rename' and 'extract' to
determine the file overwrite policy. These options are usually
combined with -v/--verbose to provide additional status output.
The options --force and --Force apply to the 'rename' command.
The 'extract' command treats --force and --Force as permission to
overwrite.
The default behaviour is to prompt the user.
-f = Do not prompt before overwriting existing files.
-F = Do not prompt before renaming files. Appends '_1' ('_2', ...)
to the name of the new file. For example:
$ curl --silent -O http://clanmills.com/Stonehenge.jpg
$ exiv2 --verbose --Force rename Stonehenge.jpg
File 1/1: Stonehenge.jpg
Renaming file to ./20150716_153854.jpg
$ curl --silent -O http://clanmills.com/Stonehenge.jpg
$ exiv2 --verbose --Force rename Stonehenge.jpg
File 1/1: Stonehenge.jpg
Renaming file to ./20150716_153854_1.jpg
The 'rename' command will only overwrite files when the option
--force is used. The option --Force is provided to avoid
unintentional loss of valuable image files.
The 'extract' command will overwrite files when either --force or
--Force is used. Overwriting extracted files will not cause the
loss of image files.
-r fmt Filename format for the 'rename' action. The format string uses
strftime(3) definitions and supports the following keywords:
:basename: original filename without extension
:dirname: name of the directory holding the original file
:parentname: name of parent directory
Note that the colons are part of the keyword.
-a time
Time adjustment in the format [-]HH[:MM[:SS]]. This option is only
used with the 'adjust' action. Examples: 1 adds one hour, 1:01
adds one hour and one minute, -0:00:30 subtracts 30 seconds. See
Exif DateTime below for additional information.
-Y yrs Time adjustment by a positive or negative number of years, for the
'adjust' action.
-O mon Time adjustment by a positive or negative number of months, for
the 'adjust' action.
-D day Time adjustment by a positive or negative number of days, for the
'adjust' action.
-p mode
Print mode for the 'print' action. Possible modes are:
s : print a summary of the Exif metadata (the default)
a : print Exif, IPTC and XMP metadata (shortcut for -Pkyct)
e : print Exif metadata (shortcut for -PEkycv)
t : interpreted (translated) Exif tags (-PEkyct)
v : plain Exif tag values (-PExgnycv)
h : hexdump of the Exif data (-PExgnycsh)
i : IPTC datasets (-PIkyct)
x : XMP properties (-PXkyct)
c : JPEG comment
p : list available image previews, sorted by preview image size in pixels
C : print image ICC Profile (jpg, png, tiff, webp, cr2, jp2 only)
R : print image structure recursively (jpg, png, tiff, webp, cr2, jp2 only)
S : print image structure information (jpg, png, tiff, webp, cr2, jp2 only)
X : print "raw" XMP (jpg, png, tiff, webp, cr2, jp2 only)
-P flgs
Print flags for fine control of the tag list ('print' action).
Allows control of the type of metadata as well as data columns
included in the print output. Valid flags are:
E : include Exif tags in the list
I : IPTC datasets
X : XMP properties
x : print a column with the tag number
g : group name
k : key
l : tag label
n : tag name
y : type
c : number of components (count)
s : size in bytes
v : plain data value (vanilla values)
V : plain data value AND the word 'set ' (for use with exiv2 -m-)
t : interpreted (translated) human readable data
h : hexdump of the data
-d tgt Delete target(s) for the 'delete' action. Possible targets are:
a : all supported metadata (the default)
e : Exif section
t : Exif thumbnail only
i : IPTC data
x : XMP packet
c : JPEG comment
C : ICC Profile
I : All IPTC data
-i tgt Insert target(s) for the 'insert' action. Possible targets are the
same as those for the -d option, plus an optional modifier:
X : Insert metadata from an XMP sidecar file <file>.xmp. The
remaining insert targets determine what metadata to insert from
the sidecar file. Possible are Exif, IPTC and XMP and the default
is all of these. Note that the inserted XMP properties include
those converted to Exif and IPTC.
XX: Insert "raw" XMP metadata from a sidecar (see option -pX)
- : Read from stdin. This option is intended for "filter"
operations such as:
$ exiv2 -e{tgt}- filename | xmllint .... | exiv2 -i{tgt}- filename
Only JPEG thumbnails can be inserted (not TIFF thumbnails), and
must be named file-thumb.jpg.
-e tgt Extract target(s) for the 'extract' action. Possible targets are
the same as those for the -d option, plus a target to extract
preview images and a modifier to generate an XMP sidecar file:
p[<n>[,<m> ...]] : Extract preview images. The optional comma
separated list of preview image numbers is used to determine which
preview images to extract. The available preview images and their
numbers are displayed with the 'print' option -pp.
C : Extract embedded ICC profile to <file>.icc
X : Extract metadata to an XMP sidecar file <file>.xmp. The
remaining extract targets determine what metadata to extract to
the sidecar file. Possible are Exif, IPTC and XMP and the default
is all of these.
XX: Extract "raw" XMP metadata to a sidecar (see -pX)
You may not use modify commands with the -eXX option and only XMP
is written to the sidecar.
- Output to stdout (see -i tgt for an example of this feature)
-c txt JPEG comment string to set in the image ('modify' action). This
option can also be used with the 'extract' and 'insert' actions to
modify metadata on-the-fly.
-m file
Command file for the 'modify' action. This option can also be used
with the 'extract' and 'insert' actions to modify metadata on-the-
fly. -m- represents standard-input.
-M cmd Command line for the 'modify' action. This option can also be used
with the 'extract' and 'insert' actions to modify metadata on-the-
fly. The format for the commands is the same as that of the lines
of a command file.
-l dir Location (directory) for files to be inserted or extracted.
-S .suf
Use suffix .suf for source files in 'insert' action.
COMMANDS
Commands for the 'modify' action can be read from a command file, e.g.,
$ exiv2 -m cmd.txt image.jpg
or given on the command line, as in
$ exiv2 -M"add Iptc.Application2.Credit String Mr. Smith" image.jpg
Note the quotes. Multiple -m and -M options can be combined, and a non-
standard XMP namespace registered.
$ exiv2 -M"reg myprefix http://ns.myprefix.me/" -M"add Xmp.myprefix.Whom Mr. Smith" -M"set Exif.Image.Artist Mr. Smith" image.jpg
When writing Exif, IPTC and XMP metadata, exiv2 enforces only a correct
metadata structure. It is possible to write tags with types and values
different from those specified in the standards, duplicate Exif tags,
undefined tags, or incomplete metadata. While exiv2 is able to read all
metadata that it can write, other programs may have difficulties with
images that contain non standard-conforming metadata.
Command format
The format of a command is
set | add | del key [[type] value]
set Set the value of an existing tag with a matching key or add the
tag.
add Add a tag (unless key is a non-repeatable IPTC key; nothing
prevents you from adding duplicate Exif tags).
del Delete all occurrences of a tag (requires only a key).
key Exiv2 Exif, IPTC or XMP key.
type Exif keys: Byte | Ascii | Short | Long | Rational | Undefined |
SShort | SLong | SRational | Comment
IPTC keys: String | Date | Time | Short | Undefined
XMP keys: XmpAlt | XmpBag | XmpSeq | LangAlt
A default type is used if none is explicitly given. The default is
determined based on key.
value The remaining text on the line is the value. It can optionally be
enclosed in single quotes ('value') or double quotes ("value").
The value is optional. Not providing any value is equivalent to an
empty value ("") and is mainly useful to create an XMP array
property, e.g., a bag.
The format of Exif Comment values include an optional charset
specification at the beginning. Comments are used by the tags
Exif.Photo.UserComment, Exif.GPSInfo.GPSProcessingMethod and
Exif.GPSInfo.GPSAreaInformation. Comments are stored as Undefined
tags with an 8 byte encoding definition follow by the encoded
data. The charset is specified as follows:
[charset=Ascii|Jis|Unicode|Undefined] comment
charset=Undefined is the default
$ exiv2 -M'set Exif.Photo.UserComment charset=Ascii My photo' x.jpg
$ exiv2 -pa --grep UserComment x.jpg
Exif.Photo.UserComment Undefined 16 My photo
$ exiv2 -pv --grep UserComment x.jpg
0x9286 Photo UserComment Undefined 16 charset=Ascii My photo
$ exiv2 -M'set Exif.Photo.UserComment charset=Unicode \u0052\u006f\u0062\u0069\u006e' x.jpg
$ exiv2 -pa --grep UserComment x.jpg
Exif.Photo.UserComment Undefined 18 Robin
$ exiv2 -pv --grep UserComment x.jpg
0x9286 Photo UserComment Undefined 18 charset=Unicode Robin
$ exiv2 -M'set Exif.GPSInfo.GPSProcessingMethod HYBRID-FIX' x.jpg
$ exiv2 -pa --grep ProcessingMethod x.jpg
Exif.GPSInfo.GPSProcessingMethod Undefined 18 HYBRID-FIX
$ exiv2 -pv --grep ProcessingMethod x.jpg
0x001b GPSInfo GPSProcessingMethod Undefined 18 HYBRID-FIX
The format for an IPTC Date value is: YYYY-MM-DD (year, month,
day)
The format for an IPTC Time value is: HH:MM:SS (hours, minutes,
seconds) and may optionally be followed by: -HH:MM or +HH:MM
(hours, minutes ahead/behind UTC)
The format of Rational (and SRational) is one of: integer |
integer/integer | Fnumber | number
Rational Examples:
$ exiv2 "-Mset Exif.Photo.MaxApertureValue 557429/62500" X.jpg
$ exiv2 "-Mset Exif.Photo.MaxApertureValue F5.6" X.jpg
The Rational format Fnumber is for the convenience of setting
aperture values. Aperture values are stored in Exif is an APEX
value which can be evaluated by the expression:
apex-value = log(Fnumber) * 2.0 / log(2.0)
number = exp(apex-value * log(2.0) / 2.0)
The Rational format Fnumber is valid for any Rational, even when
the key is not an Aperture. More information about APEX value is
available from: http://en.wikipedia.org/wiki/APEX_system
The format of XMP LangAlt values includes an optional language
qualifier:
lang="language-code" text
The double quotes around the language-code are optional. If no
languge qualifier is supplied, then the value of "x-default" is
used. More information on the language format can be found at:
https://www.ietf.org/rfc/rfc3066.txt
$ exiv2 -M'set Xmp.dc.title lang="de-DE" Euros' X.jpg
$ exiv2 -M'set Xmp.dc.title lang="en-GB" Pounds' X.jpg
$ exiv2 -M'set Xmp.dc.title lang="en-US" In God We Trust' X.jpg
$ exiv2 -M'set Xmp.dc.title lang=fr-FR Euros' X.jpg
$ exiv2 -M'set Xmp.dc.title lang=jp Yen' X.jpg
$ exiv2 -M'set Xmp.dc.title All others pay cash' X.jpg
To remove a language specification, set the value to '' (empty
string)
$ exiv2 -M'set Xmp.dc.title lang="en-US"' X.jpg
To remove all language specifications, delete the key:
$ exiv2 -M'del Xmp.dc.title' X.jpg
To register additional XMP namespaces, combine the command with:
reg prefix namespace
Command file format
Empty lines and lines starting with # in a command file are ignored
(comments). Remaining lines are commands as described above.
EXIF TAGNAMES AND VALUES
Exiv2 displays metadata tags and values.
The tag is a triplet of Family.Group.Tagname. The following groups are
defined for the family Exif:
GPSInfo Canon Fujifilm NikonMe OlympusFe7 SonyMisc2b

Exiv2 supports Exif 2.2 Standard Tags. Exiv2 also supports reading and
writing manufacturer's MakerNote. The information in
Exif.Photo.MakerNote is encoded as manufacturer's sub-records. For
example, CanonCs are Camera Settings, NikonAf are Nikon Auto Focus
records, NikonCb are Nikon Color Balance Records. Every tag is defined
by a unique tagId (16 bit integer) which is unique within a Group.
You can query Exiv2 groups and tags with the sample program taglist which
is documented in README-SAMPLES.md
Exif Metadata values are defined in the Exif Standard. All data is an
array of data elements. The Count defines the number elements in the
array. All elements in an array have the same type.
Type Explanation
1 BYTE An 8-bit unsigned integer.
2 ASCII 7-bit ASCII. NUL terminated.
3 SHORT A 16-bit (2-byte) unsigned integer.
4 LONG A 32-bit (4-byte) unsigned integer
5 RATIONAL Two LONGs. Numerator, denominator.
7 UNDEFINED An 8-bit byte.
8 SSHORT A 16-bit (2-byte) signed integer.
9 SLONG A 32-bit (4-byte) signed integer.
10 SRATIONAL Two SLONGs. Numerator, denominator.
The printing flag t = translated and is intended for human use. Scripts
should never use translated values as they are localised and the format
may change as Exiv2 evolves. The printing flag v reports the values
recorded in the metadata and should be used by scripts.
Exif DateTime
An Exif DateTime string is stored as 20 ascii bytes (including trailing
nul) in the format:
YYYY:MM:DD HH:MM:SS
The exiv2 command-line program options -t and -T will accept files in
which the Date has been incorrectly stored as YYYY-MM-DD. The option -a
enables the user to adjust the DateTime in the file and applies the
YYYY:MM:DD HH:MM:SS standard.
CONFIGURATION FILE
Exiv2 can read an optional configuration file ~/.exiv2 on Unix systems
and %USERPROFILE%\exiv2.ini on Windows (using a Visual Studio build).
Cygwin and MinGW/msys2 follow the unix convention and use ~/.exiv2 You
can determine the location of the configuration file with the command:
$ exiv2 --verbose --version --grep config_path
exiv2 0.27.0.1
config_path=/Users/rmills/.exiv2
The purpose of the configuration file is to define your own lenses for
recognition by Exiv2. The configuration file is in Windows .ini format
and has sections for each of the major camera manufactures
canon,nikon,pentax,minolta,olympus and sony. The lens metadata is stored
as a integer called the lensID. You can change the lens name associated
with any lensID.
$ cat ~/.exiv2
[nikon]
146=Robin's Sigma Lens <--- The name of your lens
You obtain the lensID for your camera with the command:
$ exiv2 -pv --grep lens/i http://clanmills.com/Stonehenge.jpg
0x0083 Nikon3 LensType Byte 1 14
0x0084 Nikon3 Lens Rational 4 180/10 2500/10 35/10 63/10

0x000c NikonLd3 LensIDNumber Byte 1 146 <--- This number
0x000d NikonLd3 LensFStops Byte 1 55
EXAMPLES
$ exiv2 *.jpg

process converts them to "IPTC Core" XMP schema.
$ exiv2 -iixX image.jpg
Inserts IPTC and XMP metadata from an XMP sidecar file image.xmp into
image.jpg. The resulting IPTC datasets are converted from the "IPTC
Core" XMP schema properties in the sidecar file to the older IPTC IIM4
format. The inserted XMP properties include those in the "IPTC Core" XMP
schema.

Sets the latitude to 4 degrees, 15 minutes and 33 seconds north. The Exif
standard stipulates that the GPSLatitude tag consists of three Rational
numbers for the degrees, minutes and seconds of the latitude and
GPSLatitudeRef contains either 'N' or 'S' for north or south latitude
respectively.
$ exiv2 -l/tmp -S.CRW insert /data/*.JPG
Copy all metadata from CRW files in the /tmp directory to JPG files with
corresponding basenames in the /data directory. Note that this copies
metadata as is, without any modifications to adapt it to the requirements
of the target format. Some tags copied like this may not make sense in
the target image.
