Processed locally — no upload. Trim Video runs entirely in your browser. Large files use more memory and processing time depends on your device. Re-encoded video is exported as WebM here (MP4 requires cross-origin isolation, e.g. a production deploy in Chrome/Firefox).

Trim video online without uploading your file

Trim Video lets you remove unwanted footage from the beginning or end of a recording by selecting the exact section you want to keep.

The video is processed locally inside your browser. Your original file remains on your device throughout the operation and is not sent to a remote processing server.

Use it for interviews, screen recordings, social clips, tutorials, presentations, family videos and any recording that needs a cleaner start or finish.

100% local processing

Your videos never leave your device.

VideoDock processes your files inside the browser tab. Nothing is uploaded to a VideoDock processing server, stored in the cloud or sent to a third-party video processing service.
