Load your video, drag the start and end handles on the scrubber to your trim points, preview the result, and export — the cut file downloads straight to your device.
No. This trimmer runs entirely in your browser on a WebAssembly build of FFmpeg, so your file never leaves your device and is never sent to a server.
MP4, WebM, MOV and most other common formats your browser can decode. The output is exported as MP4 by default.
There is no limit we impose. The practical ceiling is your device's memory — very long or high-resolution files work best on a desktop or laptop rather than a phone.
