MP3 tag editor
View and edit the ID3 tags of an MP3 — title, artist, album, year, track, genre, comment and embedded cover art — then save a re-tagged copy. Reading and writing happen entirely in your browser; the file is never uploaded.
Open MP3 tag editor →What is the MP3 tag editor?
A free, private editor for the ID3 tags inside an MP3 file — the metadata your music player shows. Load an MP3 and the tool reads its existing ID3v2 (or older ID3v1) tag: title, artist, album, album artist, year, track number, genre, comment and the embedded cover art. Edit any field, swap or remove the cover image, and save a re-tagged copy — the audio itself is copied through untouched, so there is no quality loss. Reading and writing happen entirely in your browser; the file is never uploaded.
How to use MP3 tag editor
- Load an MP3 — Drop the file onto the tool or click to choose it. The current tags and cover art fill the form.
- Edit the fields — Change the title, artist, album, year, track number, genre or comment. Separate multiple artists or genres with a semicolon.
- Update the cover art — Click Change cover to embed a JPEG or PNG image, or Remove to strip the existing artwork.
- Save — Click Save tagged MP3 — a copy with a fresh ID3v2.3 tag downloads immediately.
Frequently asked questions
Is my MP3 uploaded anywhere?
No. The tag is parsed and rewritten completely inside your browser — the tool also works offline.
Does re-tagging affect the audio quality?
No. Only the metadata block at the start of the file is replaced; the audio frames are copied byte-for-byte.
Which tag versions are supported?
The editor reads ID3v2.3, ID3v2.4 and legacy ID3v1 tags, and always writes a clean ID3v2.3 tag — the version with the widest player support.
What image should I use for cover art?
A square JPEG or PNG, ideally 500–1500 px. JPEG keeps the file smaller; players display both.
Tips
- Separate several artists or genres with semicolons — they are written as proper multi-value frames.
- Fill the album artist field on compilation tracks so albums group correctly in music players.
- The tool pairs well with the Audio converter: convert to MP3 first, then tag the result.
