How to Edit MP3 Metadata Online

Edit and save your MP3 in four steps

Open SunoSaver’s MP3 Tag Editor with an MP3 already saved on your phone or computer. The editor works with one file at a time; keep the original until you have checked the edited copy.

1. Add your MP3

   Choose “Drop an MP3 file here” and select the file, or drag it into the upload area on a computer. Existing tags are read when available. Review those values before replacing them.

   

2. Update the song details

   Enter the song name in Title and the performer or project name in Artist. Add an Album name if the track belongs to a collection. Track, Year, Genre, Composer, and Lyrics are optional; retain any existing details you want to keep.

   

3. Choose cover artwork

   To add or replace the picture, select “Choose cover artwork” under Album cover and pick an image you have permission to use. Check the preview before saving.

4. Select Save and check the downloaded copy

   Choose Save and wait for processing to finish. Find the edited MP3 in your browser’s Downloads list, then open that copy in a music player. Confirm the title, artist, album, and artwork before replacing the original in your library.

Which MP3 tags should you change?

Start with the details that are missing or incorrect. Here is an example for a track named Morning Drive; use your own song and artist details.

File name and song title are different

A file called audio_03.mp3 can still appear as “Morning Drive” in a player if its Title tag contains that name. Likewise, changing a filename to Morning Drive.mp3 does not necessarily replace an old Title tag or fix “Unknown Artist.”

Use Title and Artist to correct the player’s song display. Use the filename to recognize the file in Downloads or File Explorer. With SunoSaver, the title you enter also supplies the downloaded filename; the original filename is used when Title is blank.

Our ID3 tag guide explains how these details are stored inside an MP3.

If your player still shows the old details

First check the saved copy rather than the original. A player may still be showing the version it imported earlier.

• Open the edited MP3 directly from Downloads and inspect its title and artist in another player.
• If the new file is correct, refresh or rescan your music library, or remove the old library entry and import the edited copy again.
• If the saved copy still has the wrong fields, reopen it in the editor, review the values, and save again.
• If only the picture is missing, check the edited file in another player before changing the text tags. Artwork support and library refresh behavior vary by app.
