Video Trimmer
Cut a clip from a video locally by recording it in real time
Choose a start and end point in a local video and this tool plays that range once, capturing it live with your browser's own recording APIs, then offers the result as a download. The source video is never uploaded.
This browser does not support the capture and recording APIs this tool needs.
Choose a video to start.
This trims by playing the selected range once and recording it live with the browser's capture and recording APIs, so it takes about as long as the clip itself and the exact output codec depends on your browser. It is not frame-accurate cutting.

What this tool does
This trimmer works differently from a server-side editor: it has no video encoder of its own, so it plays your chosen range through the browser's Media Capture and MediaRecorder APIs and records that playback in real time, the same approach this site's Screen Recorder uses for a tab or window. That means trimming a clip takes about as long as the clip itself, the output container and codec depend on what your browser's recorder supports (typically WebM), and the cut points land wherever the browser's own playback and recording timing lines up, not on an exact frame. For quick clips where privacy matters more than frame-accurate editing, that trade-off keeps everything local.
How to use it
- Choose a video file and preview it to find the range you want to keep.
- Enter the start and end time in seconds.
- Start the trim, let it play and record automatically, then download the result.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Is my video uploaded to trim it?
- No. The clip is played and recorded entirely with your browser's own APIs; the file is never sent to a server.
- Why does trimming take as long as the clip?
- This tool has no video encoder of its own. It records the chosen range in real time as it plays, rather than cutting the file instantly, so a 2-minute clip takes about 2 minutes to trim.
- Is the cut frame-accurate?
- No. The start and end points depend on browser playback and recording timing, so treat them as approximate rather than exact to the frame.
