How to Trim a Video Online for Free (No Upload, No Software)

2026-05-21 4 min read

Cut a video clip, remove an awkward intro, or extract a 30-second moment โ€” entirely in your browser using FFmpeg WebAssembly. No file upload, no quality loss.

You have a 10-minute clip but only need the 90 seconds in the middle. Or you want to cut the awkward intro off a recorded call before sharing it. Trimming a video used to mean installing software like VLC, DaVinci Resolve, or Premiere. Now you can do it entirely in your browser โ€” no upload, no account, no waiting.

How Browser-Based Video Trimming Works

Our Video Clipper uses FFmpeg WebAssembly โ€” the same powerful FFmpeg that professionals use on servers, compiled to run natively in your browser. Your video never leaves your device.

Step-by-Step: Trim a Video

  1. Open the Video Clipper tool.
  2. Upload your video (MP4, MOV, WebM, MKV, AVI, FLV โ€” any format FFmpeg handles).
  3. Play the video and click "Use position" to set your start and end points, or type times directly (e.g., 0:45 to 2:30).
  4. Click "Clip Video" โ€” processing runs locally, no upload needed.
  5. Preview the result and download the trimmed clip.

Will Trimming Reduce Quality?

No. The tool uses stream copy mode (-c copy), which cuts the video without re-encoding. The output is identical quality to the original โ€” only the duration changes. The clip start point may land slightly before your selected time if the nearest keyframe is a fraction of a second earlier.
