- Add your files — drag them onto the page or choose them. They stay on your device.
- Trim silence from the start and end (the classic dead air before you start talking).
- Optionally speed the recording up, crop pixels from the top or bottom (webcam letterboxing), and set the output quality under Quality.
- Press “Tidy up” and download the results, individually or as one ZIP.
About this tool
Cut the dead air, pick up the pace and crop off the browser chrome. Free and unlimited, and nothing is uploaded: it all runs in your own browser. Everything is analysed and produced on your own device — nothing is uploaded anywhere, and you can verify it: the tools keep working even offline.
Privacy & limitations
Files over roughly 2 GB, or long 4K videos, can exhaust the browser's memory — everything runs on your machine, so your machine is the limit. Silence trimming reads the leading and trailing loudness only — long pauses in the middle are left alone by design; use remove-silence for those.

Frequently asked questions
What counts as silence?
A stretch quiet enough to be nothing, at the start and the end. Pauses in the middle are left alone, because cutting them would change the timing of what you were demonstrating.
Should I speed the recording up?
For a software demo, usually. 1.25 or 1.5 times keeps speech intelligible while removing the dead weight of waiting for pages to load.
How do I crop off the browser bar?
Set the crop from the top to the height of the chrome, which is around 90 to 140 pixels on a typical desktop browser. The crop from the bottom removes a taskbar the same way.
Will speeding it up affect the audio?
The audio is sped up with the picture and the pitch is kept, so a voice sounds faster rather than higher.
