Question 1

How does this MP3 tag editor work?

Accepted Answer

Upload one or more MP3 files, then edit the ID3v2 tags (title, artist, album, year, genre, cover art). The tool processes files entirely in your browser using the ID3Writer library — no data is ever uploaded to a server.

Question 2

Will it change my audio quality?

Accepted Answer

No. The audio frames are preserved bit-for-bit. Only the ID3 metadata block at the start of the file is rewritten with your new tags.

Question 3

Can I edit cover art?

Accepted Answer

Yes. Click the album art placeholder to pick an image (JPG or PNG). It is embedded as the front cover and stays in the downloaded MP3.

Question 4

Is my music uploaded to a server?

Accepted Answer

No. All editing happens in your browser using JavaScript. Your files never leave your device.
