Your file will stay on this device.

How to trim a video

Load your video above, set the start and end points, and export just the section you want. It is handy for cutting out dead air, grabbing a clip, or trimming a recording to fit an upload limit.

The processing runs in your browser with ffmpeg compiled to WebAssembly, so your video is never uploaded to a server.

Formats and quality

Common formats like MP4, WebM, and MOV are supported. Trimming cuts the file without re-encoding where possible, which keeps the original quality and makes the export fast.

Because everything is local, large files stay private and there are no upload waits, though very large videos depend on your device memory.
