FAQ
Does my video leave this device?▾
No. The file is read and written locally in your tab.
Why is the first run slow?▾
The browser loads the processing engine once. Later trims in the same session are faster.
Which video formats are supported?▾
Common types including MP4, MOV, WebM, MKV, M4V, and AVI, plus other video/* files your browser can read.
Why is trimming fast?▾
The tool copies the original video/audio streams without re-encoding when possible, which usually finishes in seconds. If your file cannot be copied into MP4, it falls back to a slower re-encode.
Can I trim audio-only files?▾
This tool expects a video file. For audio-only extraction, use the video-to-audio tool.
Which browsers work best?▾
Current Chrome, Edge, Firefox, and Safari versions work best for local video processing.
