Is my audio uploaded?

No. Trimming, converting and merging run in your browser, so the file stays on your device.

Which formats are supported?

The common ones: MP3, WAV, M4A and OGG, for both input and output.

Does it add a watermark or a limit?

No watermark and no length paywall. The practical limit is your device memory, since the work is local.

Yes, free with no account, supported by light advertising.

Audio jobs are often small: cut the silence off the front of a clip, convert a WAV to MP3, merge two takes, or record a quick voice note. The tools here do those without a heavy editor or an account.

Your audio stays on your device. Files are read and processed in the browser, so a recording or a private clip is not uploaded to a server.

Which tool for which job

Trim audio: Cut a clip down to the part you need and drop the rest.
Convert audio: Move between MP3, WAV, M4A and OGG when something only takes one.
Merge audio: Join several clips into one file in the order you set.
Change volume: Turn a quiet recording up or a loud one down.
Voice recorder: Capture a quick note or take from your microphone, ready to download.
