Fix the tags. Embed the art. Skip the desktop app.
Drop a file, correct its title, artist, album, and year, attach cover art, and download the fixed copy — the audio passes through untouched, only the metadata changes.
Nothing is uploaded — your audio never leaves your device.

Tags are how your music survives contact with the world
The moment a file leaves your machine — to a collaborator, a DJ pool, a car stereo —
its metadata becomes its identity. An untitled file called final_v3_MASTER.mp3
shows up as "Unknown Artist" forever. Correct tags and embedded art cost thirty seconds
here and follow the file everywhere it goes.
Under the hood this rewrites the metadata container only: ID3v2 frames for MP3, Vorbis comments for FLAC and OGG, iTunes-style atoms for M4A. The audio stream is stream-copied, untouched, bit-for-bit — so tagging is always safe, even on files you can't replace.
Frequently asked questions
How do I edit a song's metadata without installing anything?
Drop the file here, edit the fields (title, artist, album, genre, year, track), optionally attach a cover image, and hit Save. ffmpeg rewrites the metadata in your browser and hands you the corrected file — the audio itself is copied bit-for-bit, not re-encoded.
What cover art size should I use?
Square, 1000×1000 to 3000×3000 pixels, JPEG or PNG. Most players display around 600px, but stores and hi-res displays reward bigger — 3000×3000 JPEG is the safe modern standard.
Does editing tags re-encode or damage the audio?
No. The audio stream is copied unchanged ('-c copy' in ffmpeg terms); only the metadata container is rewritten. A 320 kbps MP3 stays exactly the same 320 kbps MP3.
Which formats can I tag?
MP3 (ID3), FLAC and OGG (Vorbis comments), and M4A (iTunes-style atoms). The same fields work across all of them — the tool speaks each format's native tag dialect.
