id3 mass tagger is a tool for manipulating id3 and id3v2 tags in multiple files. It can generate tag fields from the filename and other variables, and/or rename files, using an intuitive syntax. id3 currently supports old-style ID3v1 tags, Lyrics3v2, as well as the more complex ID3v2 format. This means its use is limited to audio files which use these formats, i.e. MP3.


id3 -a "Stallman" -t "Free Software Song" fs_song.mp3"

Add a simple tag to a file.

id3 mysong.mp3
id3 -v mysong.mp3

List tag info contained in file (short-form and detailed)

id3 --genre "psych rock" *.mp3

Sets genre to "Psychedelic Rock" in all mp3's

id3 --artist "TAFKAT" --track "%1" -title "%+2" "*. *.mp3"

Update tag fields similar to this;

id3 -a "TAFKAT" -n "01" -t "My Song" "01. my_song.mp3"
id3 -a "TAFKAT" -n "02" -t "Untitled" "02. untitled.mp3"

id3 -m "%n. %+t.mp3"

Shorthand notation for the above, using the -m option.

id3 -f "%a - %t.mp3" blaet.mp3

Rename file to a standard "Artist - Title" format.

id3 -g "alt rock" -a "The Author" -l %1 -n %2 -t %3 "Author - */(*) *.mp3"

Process multiple directories at once.

id3 -2 -wTPE2 "%{TXXX:ALBUM ARTIST}" file.mp3

Copy the ID3v2 album artist field (as used by Foobar2000), if any, to the field used by iTunes

id3 -1 -3 -d *.mp3

Removes all ID3v1 and Lyrics3 tags from all mp3's

id3 -2 -1 -u "*.mp3"

Copy ID3v2 tag (if any) to ID3v1 tag in all files.

id3 -a %t -t %a "*.mp3"

Swap artist and title fields in all mp3's.

id3 -D source.mp3 -1 -2 dest.mp3

Copy ID3v1 and ID3v2 tags of source.mp3 to dest.mp3

id3 -D source.mp3 -1u -2u dest.mp3

As above, but only replaces the non-standard or blank fields in dest.mp3 by data from source.mp3.

id3 -2 -rAPIC -rGEOB -s 0 *.mp3

Removes embedded images, binary blobs, and padding from all mp3's.

id3 -2 -rAPIC -rGEOB -s 0 -R "Music/*.mp3"

As above, but works recursively on all mp3's in the Music folder

id3 -2 -q "%| %a - %|Untitled|t || %t || %1 |?" "*.mp3"

Generate a playlist, using the best possible text

id3 -2 -c "Was: %_f" -f "%a - %|Untitled (%#x)|t.mp3" "*.mp3"

Advanced rename. Saves previous filename in the comment field, and renames files without proper tags to;

Unknown - Untitled (01).mp3
Unknown - Untitled (02).mp3
... etc

Fore more information, consult the documentation.


ID3v2.4 at the start of a file can be read, but will be converted to the universally recognized ID3v2.3 when written. This may actually be a feature rather than a limitation; id3 -2u is a quick way to convert tags to a form your portable player may recognize.

On Windows, support for non-ASCII characters (e.g. Russian or Korean characters) is dependent on your system language settings. A Unicode version is on the TODO list.

Developer notes

Like many small projects, this started as something hacked together to scratch a need. Besides its obvious purpose, this has also become an exercise in writing a fully portable program, trying out C++ features on various compilers, etc.

If you like this program, you can help by trying to build and test it on an uncommon system, or becoming a package maintainer for some Linux distribution. Please contact me if you do so.
