About this video trimmer

The Video Trimmer cuts a video down to just the section you want and exports it as a new clip — right in your browser, with no upload, no watermark, and no software to install.

Drop in a clip, drag the two handles along the timeline to mark where it should start and end, and preview the exact selection before you export. The tool decodes your video, plays back only the chosen range, and re-encodes it locally using your browser's built-in recorder — so your footage never touches a server. People use it to:

One honest trade-off of doing everything in the browser: re-encoding runs in real time, so a twenty-second clip takes about twenty seconds to export. In return, your video stays completely private and there is nothing to install.

How to use
  1. Upload a video with the file picker or drag it onto the drop zone — MP4, WebM, MOV, and MKV all work.
  2. Drag the two handles on the timeline to set the start and end of your clip, or move the playhead and click Set start / Set end.
  3. Press the play button to preview exactly what will be exported — it loops your selection.
  4. Pick an output format and quality if you like.
  5. Click Trim & export clip, wait for the progress bar, then download your trimmed video.
FAQ

Drag the two handles on the timeline to mark where the clip should begin and end, or move the playhead and click Set start or Set end. The selected range is highlighted and its duration is shown live.

Browsers can only re-encode video in real time via the MediaRecorder API, so a 20-second trimmed clip takes roughly 20 seconds to render. This is the trade-off for trimming locally with no upload.

WebM (VP9 or VP8 with Opus audio) works in every modern browser. On browsers that support MP4 recording, mainly Safari, an MP4 option appears too.

Yes. The audio inside your selected range is captured along with the video, so the trimmed clip keeps its sound.
