Read and rewrite ID3v1, v2.3 and v2.4 tags without re-encoding the audio
Processed in your browser. Nothing is uploaded. Checked against sources on 17 Oct 2026.Every ID3 version in use is read here: v1 and v1.1 at the end of the file, v2.2 with its three-letter frames, v2.3 and v2.4 with UTF-16 and UTF-8 text and synchsafe sizes. The edited tag is written in the version the file already had, frames this page does not show, such as lyrics or ratings, are kept unchanged, and the audio data is copied byte for byte.

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.
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.
The rest of the article, and all 6 questions about MP3 Tag Editor, are on the MP3 Tag Editor page.
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.
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.
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.
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.
