Trim Audio — frequently asked questions

Is my file uploaded?+

No — the audio is decoded, trimmed and re-encoded entirely in your browser.

Can I keep the middle and drop both ends?+

Yes — the start and end handles set the region to keep; everything outside them is removed.

What format is the output?+

MP3 or WAV, your choice. It defaults to matching the input where possible.

Is the cut sample-accurate?+

Yes — the trim happens on the decoded PCM samples, so it's precise to the frame.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
