About this tool
This free tool trims a video — you pick a start and end point and it cuts out that clip for you to download. It's perfect for grabbing a highlight, removing a boring intro, or shortening a recording before you share it.
Everything runs 100% in your browser using WebAssembly (ffmpeg). Your video is never uploaded to a server — the trim happens on your own device, so it's private and there's no file-size limit imposed by an upload.
Choose Fast mode to cut with no re-encoding — it's instant and keeps the original quality, snapping to the nearest keyframe. Choose Precise mode for a frame-accurate cut (it re-encodes to MP4, which takes a little longer). The video engine (about 30 MB) downloads once the first time you use the tool, then is cached for next time.

Frequently asked questions
Is it really free with no watermark?
Yes — it's completely free, adds no watermark, and there's no sign-up.
Is my video uploaded anywhere?
No. The trim runs in your browser on your device; the video is never sent to a server.
What's the difference between Fast and Precise?
Fast copies the video without re-encoding, so it's instant and lossless but can only cut at the nearest keyframe (the start may shift by up to a second or two). Precise re-encodes to MP4 for an exact cut, which takes longer.
Which formats can I trim?
MP4, WebM, MOV and MKV. Fast mode keeps the original format; Precise mode outputs an MP4.
