Trim video precisely, change framing and speed, rotate or mute, then export MP4 or WebM.
Use the guide alongside the working tool.
Open Video Trimmer →Start with your media
Add a video. Set exact times or use the trim sliders and preview the selection.
Shape the result
Choose size, framing, speed, rotation and audio settings.
Review and export
Prepare the cut, review the encoded video and download.
Changing controls keeps the previous export labeled as out of date until you prepare a new result. Always listen or watch before sharing.
Compatibility and limits
Files stay on your device. A pinned FFmpeg WebAssembly engine (about 31 MB) downloads from jsDelivr on first use; an internet connection and a modern WebAssembly browser are required. Processing uses one worker thread and can be slow or memory-intensive on phones. Cancel stops the worker. Export re-encodes media, strips metadata and cannot recover missing quality. Encrypted or DRM-protected media is unsupported. Up to 100 MB, 10 minutes of source and 10 minutes of output. Accurate cutting re-encodes the selection rather than making approximate keyframe-only cuts. Output is capped at 1080p with a 1920-pixel longest edge. MP4 uses H.264/AAC; WebM uses VP9/Opus. Native playback depends on browser codec support.
