Browser Audio Editor

Batch trim MP3 tracks and export each clip individually.

Load multiple MP3 files, switch between tracks in one workspace, define a separate clip for each song, preview the selection, and save every trimmed result as its own MP3.
The normalization toggle is peak normalization, which is a practical browser-side way to make clips more consistent, though it’s not the same as full LUFS loudness normalization.

Choose one or more MP3 files Build a batch, click through the list, and keep a separate clip selection for every track. You can also drag and drop MP3 files here.

How it works

The editor decodes your MP3 files locally in the browser, stores a separate clip range for each track in the batch list, and re-encodes each chosen slice as its own downloadable MP3.
