Change the title, artist, album, track number, genre and cover art of an MP3, online

Processed in your browser. Nothing is uploaded. Checked against sources on 17 Oct 2026.

MP3 Tag Editor reads the ID3 tags of an MP3 in your browser and lets you change the title, artist, album, album artist, year, track, disc, genre, comment and cover picture. ID3v1, v2.2, v2.3 and v2.4 are read, files up to 500 MB work, and the audio is copied unchanged.

Next:
  • Cut the audio Cut one or more pieces out of an audio file and save them separately or joined
  • Change the volume Make an audio file louder or quieter by an exact amount, with the clipping counted first

How to edit the tags of an MP3

3

Press Add cover or Replace cover to set the album art from a JPEG or PNG.

4

Press Save MP3 with these tags; the file downloads with the new tags and the same audio.

About MP3 Tag Editor

The names a music player shows do not come from the file name. They come from an ID3 tag stored inside the MP3, usually at its very start. A file renamed to the right song can still play as Track 01 by Unknown Artist until that tag is fixed.

What can be changed.

Field ID3 frame
Title, artist, album TIT2, TPE1, TALB
Album artist TPE2
Year TYER (v2.3) or TDRC (v2.4)
Track and disc, such as 4/12 TRCK, TPOS
Genre, with the 126 standard names suggested TCON
Comment COMM
Cover picture, JPEG or PNG APIC, front cover

How the file is written. The new tag is written in the version the file already had, so a v2.3 file stays v2.3 for older car stereos and a v2.4 file keeps its UTF-8 text. Tags with names in other scripts are stored as UTF-16 or UTF-8, so Cyrillic, Japanese and accented names survive. Frames this page does not show, such as lyrics, ratings, replay gain or chapter marks, are copied across unchanged. An ID3v1 tag at the end of the file is updated too.

The sound is untouched. Only the tag is rewritten. Every byte of audio after it is copied exactly, so there is no re-encoding and no loss of quality, and the file plays the same as before. One kilobyte of padding is left in the tag so other programs can make small edits later without rewriting the whole file.

Checks. Track and disc must be a number or number/total, and the year four digits; the Save button waits until both are right.

Tested on synthetic files with tags built by hand in every version and read back by a separate reader. Nothing is uploaded.

Frequently asked questions

How do I edit the tags of an MP3?

Drop the MP3 on MP3 Tag Editor. Its current title, artist, album, year, track, genre, comment and cover appear in boxes. Change what is wrong and press Save MP3 with these tags. The file downloads with the new tags, and any music player reads the corrected names from it.

How do I add album art to an MP3?

Open the MP3 here, press Add cover and choose a JPEG or PNG picture. The picture is stored inside the file as the front cover in an APIC frame, which phones, car stereos, iTunes and Windows Media Player all show. A square image of 500 to 1,000 pixels works best.

Does editing tags change the sound quality?

No. Only the tag at the start of the file is rewritten; every byte of audio behind it is copied exactly as it was. Nothing is decoded or re-encoded, so the song sounds identical and its bit rate, length and quality stay the same.

Why does my song still show the old name?

Many players keep a library of tags they have already read. After saving, replace the old file with the new one, then refresh the library or remove and add the song again. On a phone, restarting the music app usually makes it read the new tag.

Which ID3 versions are supported?

ID3v1 and v1.1 at the end of a file, and ID3v2.2, v2.3 and v2.4 at the start, including UTF-16 and UTF-8 text. The edited tag keeps the version the file had; a file with only v1 or v2.2 gets a v2.3 tag, which every player reads.

Is my music uploaded anywhere?

No. The MP3 is read and rewritten by your own browser, and the new file is created on your device. Nothing is sent to a server, so unreleased songs and private recordings stay private. Closing the tab clears everything.
