What Kid3 is

Kid3 is free, open-source software for editing tags on individual audio files or complete albums. It handles ID3v1.1 tags and ID3v2.3 and ID3v2.4 frames, including conversion between those versions, across formats such as MP3, FLAC, Ogg/Vorbis, MP4/AAC, Matroska/WebM, WAV, and AIFF. Batch tools apply shared values to multiple files, create tags from filenames, generate filenames from tags, and rename or create directories from tag data. Album information can be imported from gnudb.org, MusicBrainz, Discogs, Amazon, and other sources. Kid3 edits synchronized lyrics and timing codes, imports and exports LRC files, and exports tags as CSV, HTML, playlists, Kover XML, and other formats. Automation is available through QML/JavaScript, D-Bus, or the command line. Downloads cover Linux, Windows, macOS, and Android, with source code and release checksums and signatures.

Who it suits

Kid3 suits listeners and music library maintainers organizing metadata across albums and supported audio formats. It also fits users who want command-line or scriptable automation.
