What it does
This tool cuts one part out of a video you already have and saves it as a new WebM file, with or without the sound. The file is never uploaded.
Browsers cannot cut a video file directly, so the tool plays the chosen part into the browser’s own recorder. That has two honest consequences: making the clip takes as long as the clip (a 30 second clip takes about 30 seconds), and the picture is encoded again, so the quality can drop a little. To turn the clip into an animation, open it in video to GIF; to cut sound on its own, use the audio trimmer.
How to use it
- Press Open a video and choose a video your browser can play.
- Set the start and end with the sliders or the time boxes, or pause the video and press Start at the current frame or End at the current frame.
- Tick Remove the sound if you want a silent clip.
- Press Make the clip and keep the tab open until the progress bar fills, then watch the preview and press Download the clip (WebM).
What each setting does
- Start and End: the part to keep, in seconds. The end must be after the start.
- Remove the sound: saves the picture only, with no sound track.
- Cancel: stops the recording and throws away what was made so far.
While the clip is recorded, its sound goes to the recorder but not to your speakers.
Worked example
You have a 2 minute phone video and want the goal between 1:05 and 1:20. Type 65 as the start and 80 as the end. The line under the boxes reads “Clip from 65 s to 80 s: 15 s long”, and making it takes about 15 seconds. The download is named after your video, such as match-65-80s.webm.
FAQs
Can I save MP4? No, the clip is WebM, which plays in Chrome, Edge, Firefox, VLC and most editors.
Why is the clip not cut on the exact frame? The recorder starts as playback starts, so the first and last frames can differ by a fraction of a second.
Does it work on a phone? Only where the browser can record a playing video; if not, the page says so.
