About this tool

Free Batch Audio Metadata Editor

Edit metadata tags across multiple audio files at once. Set artist, title, album, copyright, year, genre and custom fields on WAV, MP3 and AIFF files. Ideal for preparing audio deliveries, music libraries and sound effect collections.

Supported tag formats

How it works

Drop your audio files, fill in the metadata fields you want to apply, then process. Tags are written directly into the files. Download individually or grab everything as a zip. All processing happens in your browser — no uploads.

Frequently asked questions

What metadata fields can I edit?

Artist, title, album, year, genre, copyright, comment, track number and more. The available fields depend on the file format — MP3 supports ID3v2, WAV uses RIFF INFO tags.

Can I apply the same metadata to multiple files?

Yes. Fill in the fields once and they are applied to all files in the batch. This is useful for setting copyright, year or album across an entire delivery.

Does it preserve audio quality?

Yes. The tool only modifies metadata — the audio data itself is untouched.

Are my files uploaded anywhere?

No. All processing runs in your browser. No files leave your machine.
