    ID3 METADATA

    Fix What Your Music Player Shows

    Renaming an MP3 file does not necessarily change the song title inside it. Players usually read embedded ID3 metadata instead: title, artist, album, track number and artwork.

    • Replace “Unknown artist” with the correct credit.
    • Restore missing album and track information.
    • Embed cover art that travels with the MP3.

    The filename can stay the same while the title, artist, album and cover shown by your player change.

    What Do You Need to Fix?

    Start from the problem you see in your player. Each path uses the same editor, but keeps the next action clear.

    FIX INCORRECT DETAILS

    Make the player show the right song

    A filename and an embedded title are separate. Update the ID3 fields your player reads, then download the corrected copy.

    1. Open the affected MP3.
    2. Correct Title, Artist and Album.
    3. Review the new display information.

    BATCH ID3 EDITING

    Edit One MP3—or Tag a Whole Album Together

    Apply the album, album artist, genre or cover to a set of tracks without overwriting details that should stay different. The batch editor makes the scope of every change visible before you save.

    • Choose exactly which fields apply to every selected file.
    • Keep individual song titles while sharing album details.
    • Auto-number tracks and create consistent filenames.
    • Download the finished album as separate files or one ZIP.

    Edit the MP3 Details That Matter

    Correct common ID3 fields first, then open advanced details only when your catalog needs them.

    How to Edit MP3 Tags Online

    The review step sits between editing and downloading, so a batch change never has to be a blind one.

    1. Choose one MP3 or an album

      Open a single file, or switch to Batch Edit for up to 10 tracks. Existing ID3 tags and cover art appear automatically.

    2. Edit the tags and artwork

      Correct the song details you need. For a batch, select only the shared fields that should be applied to every file.

    3. Review every change

      Check titles, track order, artwork and optional filename patterns before creating any updated copies.

    4. Download tagged copies

      Save one updated MP3 or download a complete batch as a ZIP. Your original files remain unchanged.

    100 MB per file Up to 10 files and 300 MB per batch JPEG or PNG cover up to 5 MB

    Update the Tags, Not the Recording

    Metadata editing stays focused on the information around your audio—not on changing the sound itself.

    Processed in your browser

    Selected files are read on this device instead of being sent to a server for tag editing.

    No audio re-encoding

    The audio stream is copied while the metadata is rewritten, so tag changes do not reduce sound quality.

    Originals stay unchanged

    Downloads are new copies. Review them first, then replace or archive the originals on your own terms.

    MP3 Tag Editor FAQs

    Answers about ID3 fields, album artwork, batch editing, audio quality, privacy and file limits.

    Is this MP3 tag editor free and private?

    Yes. Single-file editing, batch editing and downloads are free, with no sign-up or desktop app required. Your audio is read and processed locally in the browser, not uploaded for processing. The editing engine may download on first use.

    Which MP3 tags can I edit or remove?

    Edit title, artist, album, album artist, genre, year, track number and comments. Advanced fields include composer, disc number, a known BPM and plain-text lyrics. Clear a field to remove its value, then review the changes before saving.

    Can I batch-edit MP3 metadata without changing each song title?

    Yes. In Batch Edit, apply shared fields such as Album or Album artist and leave Title unchecked. Unchecked fields keep each file's existing value. You can also number tracks and rename downloaded copies from tags, using patterns such as Track - Title or Artist - Title.

    How do I add or change MP3 album art?

    Choose a JPEG or PNG up to 5 MB and 25 megapixels. A new cover replaces the file's embedded artwork with one image. You can also remove the cover or keep it unchanged. In Batch Edit, the chosen cover action applies to every readable file.

    Does editing ID3 tags change the audio quality?

    No audio re-encoding is needed: the editor copies the audio while updating its metadata. Adding a cover can increase the file size. Keep the originals as a backup because unusual or proprietary metadata may not survive the rewrite.

    Will it find missing titles, covers or lyrics automatically?

    No. Enter the song details you want to keep and choose your own cover image. This is a manual MP3 metadata editor, not an automatic song identifier or album-art lookup service. Batch numbering and filenames use your existing or edited tags.

    View all 8 questionsShow fewer questions
    Why does my music player still show the old title or cover?

    Use the updated downloaded MP3, not the original. Some players cache tags and artwork, so rescan your library or import the new copy again. Players can display tags differently, and renaming a file does not necessarily change the title shown during playback.

    What are the file limits and supported formats?

    Edit one file up to 100 MB, or a batch of up to 10 files and 300 MB total. MP3 is supported, along with M4A, M4B, FLAC, OGG and Opus. Files keep their original format; compatibility depends on the container and codec. Protected or damaged files may not work.

    Give Every MP3 the Right Title, Artist and Cover

    Open one track or a whole album, review the metadata, then download cleanly tagged copies.
