What are ID3 tags?

ID3 tags are metadata embedded inside audio files that store information about the track - title, artist, album, genre, year, track number, cover artwork, and more. They follow the ID3v2 standard, which is supported by virtually every music player, streaming platform, and DJ software.

When you upload a track to Spotify, SoundCloud, Bandcamp, or any other platform, these tags are what populate the track information. If your tags are missing or wrong, your track shows up with the wrong name, no artwork, or incorrect artist credits.

Why metadata matters

Properly tagged files make your music easier to find, organize, and distribute. Platforms like Spotify and Apple Music pull metadata directly from your files during upload. SoundCloud channels that premiere your tracks rely on clean metadata to post correctly. And if you share files with collaborators or labels, well-tagged files save everyone time.

How to edit audio metadata online

This tool lets you edit ID3 tags on your audio files directly in your browser. No software to install, no account to create. Here's how:

  1. Upload your file - drag and drop or click to upload one or more MP3 or WAV files (up to 50 MB each).
  2. Edit your tags - the tool reads any existing metadata and fills in the fields. Edit the title, artist, album, genre, year, track number, or add custom fields.
  3. Add cover artwork - upload a JPG or PNG image. The tool automatically resizes it to 500x500 for optimal embedding.
  4. Save and download - click "Save & download" to get your file with updated tags. For MP3 files, the audio data stays untouched - only the metadata is changed.

Supported metadata fields

This editor supports all standard ID3v2.3 text frames:

Cover artwork best practices

Size and format

Most platforms recommend square artwork at 3000x3000 pixels for uploads, but embedded artwork in audio files should be smaller to keep file sizes reasonable. This tool resizes images to a maximum of 500x500 pixels, which is the sweet spot for embedded artwork - detailed enough to look good in players, small enough to not bloat your file.

File format

JPEG is the standard for embedded artwork. PNG works too but creates larger files. Avoid BMP or TIFF - they're not supported by most players.

Common use cases

Before uploading to SoundCloud

Set the correct title, artist, and genre so your track displays properly. Add cover artwork so it looks professional in the feed. If you're submitting to premiere channels on Premierely, clean metadata helps channel owners process your submission faster.

Before uploading to Spotify or Bandcamp

Spotify's distributor pulls title, artist, album, and track number from your file's metadata. Bandcamp reads tags during upload to pre-fill release info. Getting metadata right before upload saves you from fixing it manually in each platform's dashboard.

Organizing your music library

DJs, producers, and label managers often need to tag large batches of files. Use the batch editing feature to upload multiple files, set shared fields across all of them, and download everything as a zip.

Frequently asked questions

Does this tool re-encode my MP3 files?

No. For MP3 files, the tool performs tag surgery - it strips the old ID3 tag and writes a new one, leaving the audio data completely untouched. Your audio quality stays exactly the same. There is zero re-encoding.

Is my audio file uploaded to a server?

No. All processing runs locally in your browser. Your files never leave your device. Nothing is uploaded, stored, or shared.

What audio formats are supported?

Full read and write support for MP3 and WAV. MP3 files use ID3v2 tags. WAV files use RIFF INFO chunks. Both formats preserve the original audio data during editing.

Can I edit multiple files at once?

Yes. Upload multiple files or an entire EP at once. Use the track navigator and tabs to switch between them. You can copy shared fields like album name, genre, and year to all tracks in one click.

What happens to my cover artwork?

Uploaded artwork is automatically resized to a maximum of 500x500 pixels and embedded as an APIC frame in the ID3 tag. This keeps the file size reasonable while maintaining good visual quality across players.

What is the maximum file size?

The recommended limit is 50 MB per file. Larger files may work depending on your device's memory. Since there's no re-encoding, processing is nearly instant regardless of file size.
