Cut videos and convert MP4/WebM free
Need to trim video online free? This video cutter removes unwanted starts and endings from your clips without uploading anything. It also works as an MP4 to WebM converter (and WebM to MP4), so your videos play nicely wherever you need them — on the web, in chats, or on social media.
The conversion engine downloads once (about 30 MB) the first time you trim or convert, then runs entirely on your device. Your videos never leave your phone or computer.
