About MusicBrainz Picard

Picard is the official tagger for the MusicBrainz database, a cross-platform application for Linux, macOS and Windows that labels audio files. It takes an album-oriented approach, so tags come from MusicBrainz release data, which helps collections get labeled consistently.

Picard handles most popular formats, including MP3, FLAC, OGG, M4A, WMA and WAV. AcoustID audio fingerprints identify files by what they sound like even if they have no metadata, and entire CDs can be looked up with a click. It can find and download cover art, and a scripting language controls exactly how files are named and how tags look.

Plugins extend the application, and users can pick from available ones or write their own. Picard has strong Unicode handling, is written in Python and is licensed under GPL-2.0 or later. Binary downloads are on the project site, with a quick-start guide and documentation for tagging.
