uploading a thing.

Frequently asked questions

Is trimming audio free?

Completely — no signup, no watermark, no limit. There is no server, so there is nothing to charge for.

Is my audio uploaded?

No. The cut happens entirely in your browser. Your audio never leaves your device.

Does trimming lose quality?

No — it's lossless. The selected section is copied without re-encoding, so it sounds identical to the original and keeps the same format.

Why is the first use slower?

The first time, your browser downloads a one-time audio engine. After that it's cached, so later edits are quick.
