Clean up a messy music library, one file at a time
"Track 01", "Unknown Artist", album art that belongs to a different record — every collection accumulates them. This editor opens the ID3v2 tag block at the front of your MP3, shows everything in editable fields, and writes a fresh, standards-clean ID3v2.3 tag with full Unicode support. The audio itself is copied byte-for-byte: no re-encoding, no quality change, and saving is instant because nothing is recompressed.
What it handles
- Reads ID3v2.2, v2.3 and v2.4 — covering files tagged by iTunes, Windows Media Player, and everything since.
- Edits title, artist, album, year, genre, track number, and embedded cover art (JPEG/PNG).
- Writes ID3v2.3 with UTF-16 text — the most compatible flavor for car stereos, old iPods and every modern player.
Cover art tips
Use a square JPEG between 500×500 and 1400×1400 px. Bigger images work but bloat every copy of the file, and some car head units silently refuse art over ~1 MB. The built-in player lets you confirm the file still plays before downloading.
FAQ
Does editing tags re-encode or degrade my MP3?
No — tags live in a separate block before the audio. Only that block is rewritten; the MPEG frames are copied bit-for-bit.
What tag fields and versions are supported?
Title, artist, album, year, genre, track and cover art. Reads ID3v2.2/2.3/2.4, writes maximally-compatible ID3v2.3 with Unicode.
What image should I use for cover art?
Square JPEG or PNG, 500–1400 px, under ~1 MB for best compatibility.
Is my music uploaded?
No — parsing and rewriting happen in your browser's memory.
