How to cut a video losslessly
Mark the parts to keep or delete, and export them without re-encoding. Each part starts on the key frame at or before your mark, so every frame is copied from the original and the export takes seconds, even for long 4K recordings. The video never leaves your device.

What to expect
- Supported inputs
- MP4, MOV, MKV, WebM, MPEG-TS, and other videos this browser’s engine can read.
- What happens
- The kept parts are copied into the source format, or MP4 when the source format can’t be written, using the main video and audio tracks. Choose Frame-exact to cut exactly where you marked; the kept parts are then re-encoded.
- Limits
- A part can only start on a key frame, often up to a few seconds before your mark. An end can fall anywhere, and may run a frame or two past it.
