Your file never leaves your device. Each tool runs in your browser and nothing is uploaded to Screencap or anyone else, so they are fine for private or work videos.

We built these small helpers alongside Screencap, our free screen recorder. Use them on the videos you record with it, or on any clip you need to convert, shrink or retime.
Screencap is a free screen recorder for the Mac, and for Chrome or Edge on Windows and Linux. Record your screen, then share a link that plays in any browser.
