Frequently asked questions

What format does the trimmed file download as?

WAV, 16-bit PCM, uncompressed. That keeps the export simple and lossless and means it opens in every audio editor. It will be larger than a compressed MP3 of the same length, that's the tradeoff for doing the encoding entirely in the browser without a server-side library.

Is my audio file uploaded anywhere?

No. The file is decoded, waveform-drawn and trimmed entirely with your browser's Web Audio API. Nothing is sent to a server, the audio stays on your device the whole time.

Can I trim more than one file at once?

You can load several files and trim and download them one at a time for free. Flick Pro adds a one-click batch export that applies the same in and out points to every loaded file, plus 0.5 second fade in/out.
