About This Tool

How do I trim a video online for free?

This trimmer cuts, splits, and merges video or audio on a frame-accurate visual timeline, entirely in your browser. Drop in a file, click where you want to cut, remove the segments you do not need, and export the result as MP4. Nothing is uploaded, so your footage stays on your device and there is no watermark.

It handles MP4, WebM, MOV, MP3, WAV and more, with undo and redo for every edit. Because the timeline is frame-based, cuts land exactly where you place them, which makes it useful for cutting intros, removing mistakes, and stitching takes together.

How It Works

Three steps, no signup

  1. 01

    Drop your file

    Drag in a video or audio file. It loads onto a visual timeline with a frame-accurate playhead.

  2. 02

    Cut, split, and merge

    Split at any frame in one click, delete segments, and re-join the parts you keep. Undo and redo any step.

  3. 03

    Export as MP4

    Render the edit on your device and download the finished file. No upload, no queue, no watermark.

FAQ

Quick answers

You can split one file into segments, delete the parts you do not want, and merge the remaining segments back together. Combining separate files is on the roadmap.

MP4, WebM, and MOV for video, plus MP3 and WAV for audio. Export is MP4 (H.264).
