Read and rewrite the ID3 tags on an MP3 file: title, artist, album, year, genre and album art — all edited locally on your device.
The Audio Metadata Editor reads and writes ID3v2 tags in MP3 files: title, artist, album, album artist, year, track number, genre, composer, comment and cover art. Clean tags make a library searchable and make files show the right name and artwork on phones, cars and streaming boxes.
Unlike converters that re-encode, this editor changes only the tag block: the MPEG audio frames are copied byte-for-byte, so there is no quality loss and the file saves in a flash even for hour-long recordings.
The tag is rewritten as ID3v2.3, the most widely supported version. Text that is plain Latin-1 is stored as ISO-8859-1; anything else (accents, Cyrillic, CJK, emoji) is stored as UTF-16 with a byte-order mark. A trailing ID3v1 block is removed so players do not read stale data. Frames the editor does not touch (such as lyrics) are preserved when the source tag is v2.3. 256 bytes of padding are left so other tools can edit the tag in place.

| Tag format | ID3v2.3 (UTF-16 for non-Latin text) |

| Cover art | JPEG/PNG |
No; audio frames are not changed.
Yes, unknown frames in v2.3 tags are preserved.
No — only the ID3 tag data at the start of the file is replaced. The audio stream itself is copied byte-for-byte, so there's zero quality loss.
Yes — upload a JPG or PNG in the Cover art field before saving.
ID3 tags are an MP3-specific standard, so this tool is built for MP3 files. Other formats use different tagging systems and aren't supported here.
This tool runs entirely in your browser using the Web Audio API. Nothing is uploaded, stored or shared — there is no server to send your file to, so it works offline once the page has loaded.
