MusicBrainz Picard is a powerful, open-source music tag editor available on Windows, Mac, and Linux. It uses AcoustID audio fingerprinting to identify tracks, even without metadata. That makes it especially useful for older or poorly tagged FLAC files. If you love clean libraries and use mostly mainstream music, it’s a fantastic, free solution. The FLAC tag editor supports major formats like FLAC, MP3, and OGG, and leverages the extensive MusicBrainz database to automatically fill in accurate song details.

For Organizing Folders – TagScanner

TagScanner provides flexible editing for FLAC tags and works seamlessly with many additional audio formats. Its biggest strength lies in powerful batch processing, you can quickly rename files and organize large music folders with minimal effort. The FLAC tag editor also pulls tag info from online sources like Discogs and MusicBrainz. While the interface may seem complex at first, especially for beginners, its export options (like HTML or Excel) make it a solid choice for serious music collectors.

For Linux Users – Kid3

Kid3 is a solid pick, especially if you’re on Linux. It’s open-source and works on different platforms, handling lots of formats like FLAC, MP3, and Ogg. The interface might look a little old-school, but it gives you great control over your FLAC metadata, you can batch edit, use scripts, and even customize how tags are mapped. That said, Kid3 is better suited for experienced users who don’t mind trading a modern UI for flexibility and precision.

For Large Libraries – MediaMonkey

It excels at precise FLAC tag editing, automatically fetching accurate metadata and organizing music covers seamlessly. Its batch renaming and device syncing features make managing thousands of tracks much easier.

For Beginners – Music Tag

Music Tag provides a hassle-free way to automatically tag your FLAC files. It’s easy to install and use on both Windows and macOS, supporting popular formats, including FLAC. What I liked most is its automation, it scans your files and fills in missing metadata from its online database once you enter the title and artist. That said, it sometimes misses or gets information wrong, especially with rare tracks, so I had to tweak some tags manually.

For Batch Editing – TigoTago

While I hadn’t heard much about TigoTago FLAC tag editor before trying it, it’s been around for some time, especially popular with individuals who enjoy working in spreadsheets. Its Excel-like interface makes bulk editing tags feel familiar and efficient, which is great if you’re handling a number of files at once. However, it’s only available on Windows and lacks automatic metadata lookup, so it’s best if you don’t mind doing some manual work. Still, for organized batch editing, it’s a solid choice.
