12 exiv2 is a program to read and write Exif, IPTC, XMP metadata and image
13 comments and can read many vendor makernote tags. Users who build
14 exiv2 and its library also build some sample and test applications.
15 The samples are:
16 exiv2json Format metadata in json
17 exifprint Print the metadata in one or more images
18 The following image formats are supported:
19 Type Exif IPTC XMP Image comments

46 · Support for GIF, TGA and BMP images is minimal: the image format is
48 recognized, a MIME type assigned to it and the height and width of
49 the image are determined.
50 · Reading other TIFF-like RAW image formats, which are not listed in
52 the table, may also work.

55 The action argument is only required if it is not clear from the
56 options which action is implied.
57 pr | print
59 Print image metadata. This is the default action, i.e., the com‐
60 mand exiv2 image.jpg will print a summary of the image Exif
61 metadata.
62 ex | extract
64 Extract metadata to *.exv, XMP sidecar (*.xmp) and thumbnail
65 image files. Modification commands can be applied on-the-fly.
66 in | insert
68 Insert metadata from corresponding *.exv, XMP sidecar (*.xmp)
69 and thumbnail files. Use option -S .suf to change the suffix of
70 the input files. Since files of any supported format can be used
71 as input files, this command can be used to copy the metadata
72 between files of different formats. Modification commands can be
73 applied on-the-fly.
74 rm | delete
76 Delete image metadata from the files.
77 ad | adjust
79 Adjust Exif timestamps by the given time. Requires at least one
80 of the options -a time, -Y yrs, -O mon or -D day.
81 mo | modify
83 Apply commands to modify (add, set, delete) the Exif, IPTC and
84 XMP metadata of image files. Requires option -c, -m or -M.
85 mv | rename
87 Rename files and/or set file timestamps according to the Exif
88 create timestamp. Uses the value of tag Exif.Photo.DateTimeOrig‐
89 inal or, if not present, Exif.Image.DateTime to determine the
90 timestamp. The filename format can be set with -r fmt, timestamp
91 options are -t and -T.
92 fi | fixiso
94 Copy the ISO setting from one of the proprietary Nikon or Canon
95 makernote ISO tags to the regular Exif ISO tag,
96 Exif.Photo.ISOSpeedRatings. Does not overwrite an existing stan‐
97 dard Exif ISO tag.
98 fc | fixcom
100 Fix the character encoding of Exif Unicode user comments.
101 Decodes the comment using the auto-detected or specified charac‐
102 ter encoding and writes it back in UCS-2. Use option -n to spec‐
103 ify the current encoding of the comment if necessary.

159
162 -h Display help and exit.
163 -V Show the program version and exit.
165 When -V is combined with -v (Verbose version), build information
166 is printed to standard output along with a list of shared
167 libraries which have been loaded into memory. Verbose version is
168 supported on Windows (MSVC, Cygwin and MinGW builds), MacOSX and
169 Linux and is provided for test and debugging.
170 -v Be verbose during the program run.
172 -q Silence warnings and error messages from the Exiv2 library dur‐
174 ing the program run (quiet). Note that options -v and -q can be
175 used at the same time.
176 -Q lvl Set the log-level to 'd'(ebug), 'i'(nfo), 'w'(arning), 'e'(rror)
178 or 'm'(ute). The default log-level is 'w'. -Qm is equivalent to
179 -q. All log messages are written to standard error.
180 -b Show large binary values (default is to suppress them).
182 -u Show unknown tags (default is to suppress tags which don't have
184 a name).
185 -g key Only keys which match the given key (grep).
187 Multiple -g options can be used to grep info for several keys.
188 When the library is build with C++11, keys are matched using
189 std::regex::extended. When build without C++11, keys are pro‐
190 cessed with the system regular expression engine: see man 3
191 regex. Platforms which do not support regex use key for a sub‐
192 string match. You can determine the availability of regex using
193 the command: exiv2 -v -V -g have_regex -g cplusplus.
194 exiv2 -g Date -pt R.jpg
196 Exif.Image.DateTime Ascii 20 2012:08:07 16:01:05
197 Exif.Photo.DateTimeOriginal Ascii 20 2011:09:18 16:25:48
198 Exif.Photo.DateTimeDigitized Ascii 20 2011:09:18 16:25:48
199 -g (--grep) is only applied to keys. It is not generally
201 applied to all output such as the default -ps report.
202 The key may finish with the optional modifier /i to indicated
204 case insensitive.
205 -K key Only report data for given key.
207 Multiple -K options can be used to report more than a single
208 key.
209 exiv2 -K Exif.Photo.DateTimeDigitized -K Exif.Photo.DateTimeOriginal -pt R.jpg
211 Exif.Photo.DateTimeOriginal Ascii 20 2011:09:18 16:25:48
212 Exif.Photo.DateTimeDigitized Ascii 20 2011:09:18 16:25:48
213 -n enc Charset to use to decode Exif Unicode user comments. enc is a
215 name understood by iconv_open(3), e.g., 'UTF-8'.
216 -k Preserve file timestamps when updating files (keep). Can be used
218 with all options which update files. The flag is ignored by
219 read-only options.
220 -t Set the file timestamp according to the Exif create timestamp in
222 addition to renaming the file (overrides -k). This option is
223 only used with the 'rename' action.
224 -T Only set the file timestamp according to the Exif create time‐
226 stamp, do not rename the file (overrides -k). This option is
227 only used with the 'rename' action. Note: On Windows you may
228 have to set the TZ environment variable for this option to work
229 correctly.
230 -f Do not prompt before overwriting existing files (force over‐
232 write).
233 -F Do not prompt before renaming files (Force rename). Appends '_1'
235 ('_2', ...) to the name of the new file.
236 -a time
238 Time adjustment in the format [-]HH[:MM[:SS]]. This option is
239 only used with the 'adjust' action. Examples: 1 adds one hour,
240 1:01 adds one hour and one minute, -0:00:30 subtracts 30 sec‐
241 onds.
242 -Y yrs Time adjustment by a positive or negative number of years, for
244 the 'adjust' action.
245 -O mon Time adjustment by a positive or negative number of months, for
247 the 'adjust' action.
248 -D day Time adjustment by a positive or negative number of days, for
250 the 'adjust' action.
251 -p mode
253 Print mode for the 'print' action. Possible modes are:
254 s : print a summary of the Exif metadata (the default)
255 a : print Exif, IPTC and XMP metadata (shortcut for -Pkyct)
256 t : interpreted (translated) Exif tags (-PEkyct)
257 v : plain Exif tag values (-PExgnycv)
258 h : hexdump of the Exif data (-PExgnycsh)
259 i : IPTC datasets (-PIkyct)
260 x : XMP properties (-PXkyct)
261 c : JPEG comment
262 p : list available image previews, sorted by preview image size
263 in pixels
264 S : print image structure information (jpg, png and tiff only)
265 X : print "raw" XMP (jpg, png and tiff only)
266 -P flgs
268 Print flags for fine control of the tag list ('print' action).
269 Allows control of the type of metadata as well as data columns
270 included in the print output. Valid flags are:
271 E : include Exif tags in the list
272 I : IPTC datasets
273 X : XMP properties
274 x : print a column with the tag number
275 g : group name
276 k : key
277 l : tag label
278 n : tag name
279 y : type
280 c : number of components (count)
281 s : size in bytes
282 v : plain data value
283 V : plain data value AND the word 'set ' at the start of line
284 (for use with exiv2 -m-)
285 t : interpreted (translated) data
286 h : hexdump of the data
287 -d tgt Delete target(s) for the 'delete' action. Possible targets are:
289 a : all supported metadata (the default)
290 e : Exif section
291 t : Exif thumbnail only
292 i : IPTC data
293 x : XMP packet
294 c : JPEG comment
295 -i tgt Insert target(s) for the 'insert' action. Possible targets are
297 the same as those for the -d option, plus an optional modifier:
298 X : Insert metadata from an XMP sidecar file <file>.xmp. The
300 remaining insert targets determine what metadata to insert from
301 the sidecar file. Possible are Exif, IPTC and XMP and the
302 default is all of these. Note that the inserted XMP properties
303 include those converted to Exif and IPTC.
304 This is option is intended for "filter" operations on the XMP
305 such as:
306 $ exiv2 -e{tgt}- filename | xmllint .... | exiv2 -i{tgt}- file‐
307 name
308 Only JPEG thumbnails can be inserted (not TIFF thumbnails), they
310 need to be named file-thumb.jpg.
311 -e tgt Extract target(s) for the 'extract' action. Possible targets are
313 the same as those for the -d option, plus a target to extract
314 preview images and a modifier to generate an XMP sidecar file:
315 p[<n>[,<m> ...]] : Extract preview images. The optional comma
316 separated list of preview image numbers is used to determine
317 which preview images to extract. The available preview images
318 and their numbers are displayed with the 'print' option -pp.
319 X : Extract metadata to an XMP sidecar file <file>.xmp. The
321 remaining extract targets determine what metadata to extract to
322 the sidecar file. Possible are Exif, IPTC and XMP and the
323 default is all of these.
324 - : Output sidecar file to stdout (see -i tgt for example)
326 -r fmt Filename format for the 'rename' action. The format string fol‐
329 lows strftime(3) and supports the following keywords:
330 :basename: - original filename without extension
331 :dirname: - name of the directory holding the original file
332 :parentname: - name of parent directory
333 Default filename format is %Y%m%d_%H%M%S.
334 -c txt JPEG comment string to set in the image ('modify' action). This
336 option can also be used with the 'extract' and 'insert' actions
337 to modify metadata on-the-fly. -m- represents standard-input.
338 -m file
340 Command file for the 'modify' action. This option can also be
341 used with the 'extract' and 'insert' actions to modify metadata
342 on-the-fly.
343 -M cmd Command line for the 'modify' action. This option can also be
345 used with the 'extract' and 'insert' actions to modify metadata
346 on-the-fly. The format for the commands is the same as that of
347 the lines of a command file.
348 -l dir Location (directory) for files to be inserted or extracted.
350 -S .suf
352 Use suffix .suf for source files in 'insert' action.
353
355 Commands for the 'modify' action can be read from a command file, e.g.,
356 exiv2 -m cmd.txt image.jpg
358 or given on the command line, as in
360 exiv2 -M"add Iptc.Application2.Credit String Mr. Smith" image.jpg
362 Note the quotes. Multiple -m and -M options can be combined, and a non-
364 standard XMP namespace registered.
365 exiv2 -M"reg myprefix http://ns.myprefix.me/" -M"add Xmp.myprefix.Whom Mr. Smith" -M"set Exif.Image.Artist Mr. Smith" image.jpg
367 When writing Exif, IPTC and XMP metadata, exiv2 enforces only a correct
369 metadata structure. It is possible to write tags with types and values
370 different from those specified in the standards, duplicate Exif tags,
371 undefined tags, or incomplete metadata. While exiv2 is able to read all
372 metadata that it can write, other programs may have difficulties with
373 images that contain non standard-conforming metadata.
374 Command format
376 The format of a command is
377 set | add | del key [[type] value]
379 set Set the value of an existing tag with a matching key or add the
381 tag.
382 add Add a tag (unless key is a non-repeatable IPTC key; nothing pre‐
384 vents you from adding duplicate Exif tags).
385 del Delete all occurrences of a tag (requires only a key).
387 key Exiv2 Exif, IPTC or XMP key.
389 type Byte | Ascii | Short | Long | Rational | Undefined | SShort |
391 SLong | SRational | Comment for Exif keys,
392 String | Date | Time | Short | Undefined for IPTC keys, and
393 XmpText | XmpAlt | XmpBag | XmpSeq | LangAlt for XMP keys.
394 A default type is used if none is explicitly given. The default
396 is determined based on key.
397 value The remaining text on the line is the value. It can optionally
399 be enclosed in single quotes ('value') or double quotes
400 ("value").
401 The value is optional. Not providing any value is equivalent to
403 an empty value ("") and is mainly useful to create an XMP array
404 property, e.g., a bag.
405 The format of Exif Comment values includes an optional charset
407 specification at the beginning:
408 [charset=Ascii|Jis|Unicode|Undefined ]comment
409 Undefined is used by default if the value doesn't start with a
411 charset definition.
412 The format for an IPTC Date value is:
414 YYYY-MM-DD (year, month, day)
415 The format for an IPTC Time value is:
417 HH:MM:SS (hours, minutes, seconds)
418 and may optionally be followed by:
419 -HH:MM or +HH:MM (hours, minutes ahead/behind UTC)
420 The format of Rational (and SRational) is one of:
422 integer
423 integer-numerator/integer-denominator
424 Fnumber
425 fnumber
426 Rational Examples:
428 exiv2 "-Mset Exif.Photo.MaxApertureValue 557429/62500" X.jpg
429 exiv2 "-Mset Exif.Photo.MaxApertureValue F5.6" X.jpg
430 The Rational format Fnumber (or fnumber) is for the convenience
432 of setting aperture values. Aperture values are stored in Exif
433 is an APEX value which can be evaluated by the expression:
434 apex-value = log(Fnumber) * 2.0 / log(2.0)
436 Fnumber = exp(apex-value * log(2.0) / 2.0)
437 The Rational format Fnumber is valid for any Rational, even when
439 the key is not an Aperture. More information about APEX value
440 is available from: http://en.wikipedia.org/wiki/APEX_system
441 The format of XMP LangAlt values includes an optional language
443 qualifier:
444 lang="language-code" text
445 lang="x-default" is used if the value doesn't start with a lan‐
447 guage qualifier.
448 exiv2 -M'set Xmp.dc.title lang="de-DE" Euros' X.jpg
450 exiv2 -M'set Xmp.dc.title lang="en-GB" Pounds' X.jpg
451 exiv2 -M'set Xmp.dc.title lang="en-US" In God We Trust'
452 X.jpg
453 exiv2 -M'set Xmp.dc.title All others pay cash' X.jpg
454 To remove a language specification, set the value to '' (empty
456 string)
457 exiv2 -M'set Xmp.dc.title lang="en-US"' X.jpg
458 To remove all language specifications, delete the key:
460 exiv2 -M'del Xmp.dc.title' X.jpg
461 To register additional XMP namespaces, combine the command with:
463 reg prefix namespace
465 Command file format
467 Empty lines and lines starting with # in a command file are ignored
468 (comments). Remaining lines are commands as described above.
469
471 exiv2 *.jpg
472 Prints a summary of the Exif information for all JPEG files in
473 the directory.
474 exiv2 -pi image.jpg
476 Prints the IPTC metadata of the image.
477 exiv2 rename img_1234.jpg
479 Renames img_1234.jpg (taken on 13-Nov-05 at 22:58:31) to
480 20051113_225831.jpg
481 exiv2 -r':basename:_%Y%m' rename img_1234.jpg
483 Renames img_1234.jpg to img_1234_200511.jpg
484 exiv2 -et img1.jpg img2.jpg
486 Extracts the Exif thumbnails from the two files into
487 img1-thumb.jpg and img2-thumb.jpg.
488 exiv2 -it img1.jpg img2.jpg
490 Inserts (copies) metadata from img1.exv to img1.jpg and from
491 img2.exv to img2.jpg.
492 exiv2 -ep1,2 image.jpg
494 Extracts previews 1 and 2 from the image to the files image-pre‐
495 view1.jpg and image-preview2.jpg.
496 exiv2 -eiX image.jpg
498 Extracts IPTC datasets into an XMP sidecar file image.xmp and in
499 the process converts them to "IPTC Core" XMP schema.
500 exiv2 -iixX image.jpg
502 Inserts IPTC and XMP metadata from an XMP sidecar file image.xmp
503 into image.jpg. The resulting IPTC datasets are converted from
504 the "IPTC Core" XMP schema properties in the sidecar file to the
505 older IPTC IIM4 format. The inserted XMP properties include
506 those in the "IPTC Core" XMP schema.
507 exiv2 -M"set Exif.Photo.UserComment charset=Ascii New Exif comment" image.jpg
509 Sets the Exif comment to an ASCII string.
510 exiv2 -M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" \
512 -M"set Exif.GPSInfo.GPSLatitudeRef N" image.jpg
513 Sets the latitude to 4 degrees, 15 minutes and 33 seconds north.
514 The Exif standard stipulates that the GPSLatitude tag consists
515 of three Rational numbers for the degrees, minutes and seconds
516 of the latitude and GPSLatitudeRef contains either 'N' or 'S'
517 for north or south latitude respectively.
518 exiv2 insert -l/tmp -S.CRW /data/*.JPG
520 Copy all metadata from CRW files in the /tmp directory to JPG
521 files with corresponding basenames in the /data directory. Note
522 that this copies metadata as is, without any modifications to
523 adapt it to the requirements of the target format. Some tags
524 copied like this may not make sense in the target image.
