Video Trim Experimental

Select start and end times, preview the clip, and export WebM when your browser supports it.

Experimental & heavy. Browser-only trimming re-encodes the selected range in real time using Canvas + MediaRecorder. Output is WebM, not MP4. Large videos are slow and memory-heavy. For exact MP4 cuts use a desktop editor or ffmpeg.

Your media stays in your browser. Nothing is uploaded.

Upload a video to set trim points.
