How it works

On-device: a WebAssembly build of FFmpeg trims and re-encodes each file inside your browser tab. Nothing is uploaded anywhere.
Same trim, every file: the start/end you set is applied to every file in the batch -- handy for cutting a fixed intro or outro off a set of recordings.

Free vs Premium

Free processes one file at a time, up to 192kbps. Premium raises that to a batch of 10 files at up to 320kbps.
