Opening Edit Audio Tags…
No uploads. Runs entirely in your browser.
Edit ID3 tags and embed album cover art into your audio track.
Is FormatGrid really 100% free?
Yes. Editing audio metadata and ID3 tags on FormatGrid is completely free, with no watermarks, file limits, or account sign-up required.
Where are my uploaded audio files stored?
Nowhere. Your audio files never leave your device — FormatGrid never uploads, transmits, or stores them on any server. All metadata editing happens locally in your browser's memory and is discarded once you close or refresh the tab.
What metadata fields and tag standards can I edit?
FormatGrid writes standard ID3v2 tags directly into your audio header streams. You can edit Title, Artist, Album Name, Release Year, Genre, Track Number, and attach custom front cover artwork (JPEG or PNG).
