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
- ID3v2 tags for MP3 files — artist, title, album, year, genre, comment and more
- RIFF INFO tags for WAV files — IART, INAM, ICOP, ICRD and other standard fields
- AIFF metadata support
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?
Title, artist, album, year, genre, copyright, URL and comment. Only the fields you fill in are changed — everything else already in the file (track number, ISRC, cover art, cue markers) is kept. WAV uses RIFF INFO tags, which have no URL field; MP3 uses ID3v2; AIFF gets its native text chunks plus an ID3 chunk.
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.
