About this tool
Audio files carry ID3 tags - metadata like title, artist, album, genre, and track number - that music players use to display and organize your library. This tool lets you view and edit these tags directly, useful for fixing incorrect track info or organizing a collection of files that are missing proper metadata.
How to use this tool

- Edit tag valuesUpdate title, artist, album, genre, year, and track order details.
- Save updated metadataWrite corrected tags while preserving original audio signal.
- Re-import into playerRefresh media library so new tags appear consistently.
Fixing "Unknown Artist" in your music library
Music players read the title, artist and album from the ID3 tags inside each file, not from the file name. A song that shows as "Unknown Artist" simply has empty tags. Fill in the artist, album and track number, and use the same album name for every track so they group together.
After editing, some players need a library refresh or rescan before the new details appear.

Frequently asked questions
Common fields include title, artist, album, genre, track number, and year - the core metadata most music players use to organize and display your library.
No - metadata is separate from the audio itself; editing tags doesn't alter the sound of the track in any way.
Most players will reflect the updated tags the next time they scan/refresh the file - some players may need a manual library rescan to pick up the change immediately.
Album art is stored as an image inside the ID3 tag (an APIC frame). Where the editor supports a cover image, use a square JPG or PNG of around 500-1000 px; much larger images bloat every copy of the file.
The file has no artist tag, or the player is reading an older tag version. Fill in Artist, Album and Title here and save; most players then pick up the new details after a library rescan.
Artist names who performs each track; Album Artist names who the album belongs to. Setting the same Album Artist on every track keeps a compilation or a featuring-heavy album together in one place instead of splitting it into many artists.
