Audio Metadata Editor
Edit title, artist, album and cover art inside MP3 files. Upload a song, fix the tags in the form below and download the retagged MP3 with the audio stream untouched.
ID3 tags
A new ID3v2.3 tag is written; the audio data itself is copied unchanged. Confirm anything important against the official tag standards.
How to use
- Upload your MP3 file and wait for the current tags to load.
- Edit title, artist, album, year, genre, track number or replace the cover art.
- Click Save tags and download the retagged MP3.
Note: some players cache old tags. If the old info still shows, close and reopen the player.
Tips
- Keep cover art under 500 KB so the file stays small and loads fast.
- Use consistent artist and album names across your collection so players group songs correctly.
- Leave a field empty to remove that tag instead of guessing a value.
Frequently Asked Questions (FAQ)
Which tags can I edit?
You can edit title, artist, album, year, genre, track number and the embedded cover art image.
Is the audio quality changed?
No. The tool rebuilds only the ID3 tag header and copies the audio stream byte for byte, so quality stays exactly the same.
Is my file uploaded anywhere?
No. The MP3 is parsed and rebuilt entirely in your browser, so your file never leaves your device.
Does it only work with MP3 files?
Yes. It edits ID3 tags, which is the tag format used by MP3 files.
Can I change the cover art picture?
Yes. Use the Replace cover art option to embed a new image in the MP3.
