Free online video trimmer for fast, private cuts

How it works

Trim a video or extract MP3 in four simple steps — all in your browser.

1. Step 1

   Choose your video

   Select an MP4, MOV, or AVI file from your device. It stays on your device — nothing is uploaded.

2. Step 2

   Set the start and end

   Drag the start and end handles, or nudge them with the arrow keys for frame-accurate precision.

3. Step 3

   Trim or extract MP3

   Trim the video to your selection, or extract just the audio as an MP3 — all processed locally.

4. Step 4

   Download the result

   Save your trimmed video or extracted MP3 straight back to your device.
