How it works
- 01
Choose a video from your device. It is read locally; nothing is sent anywhere.
- 02
Set the options — range, format or quality — and press Run.
- 03
Download the result. Cutting and muting copy the original streams and finish in seconds.
About this tool
Enter a start and end time and the tool copies every packet in between into a new file. Because nothing is decoded, a two-gigabyte recording cuts as fast as your disk can read it and the output is exactly as sharp as the source. Cuts start on the nearest keyframe before your start time — usually within a second or two on web video — and the result shows the actual range used.
Questions
- Which video formats work?
- MP4, MOV, WebM and MKV. AVI, WMV and FLV are not readable in a browser yet; convert them on your computer first.
- Is the quality reduced?
- Trim and Mute copy the original video packets, so quality is identical. Convert and Compress re-encode using the codecs built into your browser.
- Why is there a size limit?
- Files up to 500 MB are free; browser memory is the real ceiling. Plus raises the limit to 4 GB.
