About this tool
Video Trim cuts a clip down to just the part you want to keep, right in your browser. Scrub to where you want it to start, mark it, then do the same for the end, and download the trimmed result. Since it re-renders the clip frame by frame, exporting takes about as long as the trimmed clip itself. Nothing ever leaves your device.
The original audio track passes straight through to the trimmed output untouched, alongside the re-rendered video. The output format is whichever your browser supports best -- some browsers (like Safari) can record directly to MP4, while others fall back to WebM -- so the exact file format can vary depending on which browser you're using.
Frequently asked questions
Why does exporting take as long as the trimmed clip itself?
This tool re-renders the video frame by frame in real time rather than decoding and re-encoding it faster than playback speed, so exporting a 2-minute clip takes about 2 minutes. That's the tradeoff for doing this entirely in the browser with no heavier video-processing library involved.
Does the trimmed video keep its original audio?
Yes -- the original audio track passes straight through to the trimmed output, alongside the re-rendered video, so you don't lose sound when you trim.
What file format will I get?
Whichever your browser supports best. Some browsers can record directly to MP4; others fall back to WebM. Both play normally in modern browsers and media players, but the exact format can vary depending on which browser you used.
Is there a minimum length for a trimmed clip?
Practically, yes -- the start and end points need to be at least a fraction of a second apart, since a clip needs some actual duration to export. There's no meaningful maximum beyond your video's own original length.
