Video Trimmer
Cut any video to a specific range without re-encoding. Fast and lossless, fully browser-based.
How Video Trimmer works
Any format supported by ffmpeg (MP4, MOV, WEBM, MKV, AVI).
Enter timestamps in seconds. The tool uses stream-copy — no re-encoding, no quality loss.
The output is instant since bytes are just copied within the range.
Frequently asked
Is it lossless?+
Yes — stream copy re-packages the same bytes without re-encoding, so quality is bit-identical to the source in the trimmed range.
Why did my trim start a little late?+
Stream-copy cuts on the nearest keyframe. For frame-accurate cuts, use the Video Converter which re-encodes.
Is my video uploaded?+
Never. Everything runs in your browser via ffmpeg.wasm.
