How to edit MP3 tags online
- Drop an MP3 into the upload box — its existing ID3 tags and cover art load into the form.
- Edit any field: title, artist, album, year, genre, track number and comment.
- Replace the cover with a JPEG or PNG, or extract the current artwork as an image.
- Save the tagged MP3 — the audio is copied through unchanged, only the tag is new.
This MP3 tag editor online fixes the metadata mess that builds up in every music folder: tracks labeled "Track 01", missing artists, wrong years, no artwork. It parses the file's ID3 tag directly in your browser, lets you correct every common field, and writes a fresh, standards-compliant tag in front of the original audio bytes — no re-encoding, no quality loss, no upload. The saved file plays everywhere the original did, just with the right name on the screen.
It is handy for cleaning up purchased downloads, labeling your own exports and demos before sending them out, and embedding cover art so albums look right on phones and in cars. For artwork in FLAC files, use the companion FLAC Cover Art tool.
FAQ
Does editing MP3 tags reduce the audio quality?
No. Only the metadata block at the front of the file is rewritten — the MP3 audio bytes are copied through completely untouched, with no decoding or re-encoding involved. The music in the saved file is bit-for-bit identical to the original.
Which tag fields and versions are supported?
The editor reads existing ID3v2.3 and ID3v2.4 tags and lets you edit title, artist, album, year, genre, track number, a comment and the embedded cover art. When you save, it writes a clean ID3v2.3 tag with UTF-16 text, which virtually every player, phone and car stereo understands.
Can I add or extract album cover art?
Both. The current cover is shown as a preview; you can replace it with any JPEG or PNG, or download the existing artwork as an image file with the Extract button. The new cover is embedded when you save the tagged MP3.
Is this MP3 tag editor free, and do my files stay on my device?
Yes and yes. Tag parsing and writing are done byte-by-byte in your browser, so the MP3 is never uploaded anywhere — useful for private recordings as well as your music library. There is no account, no limit and no watermarking of any kind.
