About The Video Trimmer & Muter

Easily slice your MP4 or WEBM video files and remove the background audio track.

Unlike cloud-based tools, this tool uses FFmpeg WebAssembly to execute a direct 'stream copy' (-c copy) entirely inside your browser. This means your video is trimmed instantly with 100% preservation of the original HD quality!

How to Use

  1. Upload a video file.
  2. Use the built-in video player to find the exact moments you want to start and stop.
  3. Click the 📍 pin button next to 'Start Time' and 'End Time' to automatically copy the player's timestamp down to the millisecond.
  4. Check 'Mute Video' if you want to completely delete the audio track.
  5. Click Trim & Export, then download your final file!

Frequently Asked Questions

Is there any quality loss when trimming?

No. This tool does not re-encode your video. It slices the binary stream directly, meaning the exported file retains 100% of the original visual quality.

Are my files private?

Yes. This tool runs the industry-standard FFmpeg engine directly inside your web browser. Your video files never leave your device.
