About The Video Compressor

Massively reduce the file size of massive videos so you can attach them to emails or upload them to Discord.

This tool uses FFmpeg WebAssembly to re-encode the video locally in your browser. It leverages the highly efficient `libx264` codec and Constant Rate Factor (CRF) scaling.

How to Use

  1. Upload a video file.
  2. Select a target resolution. For maximum file size reduction, drop 1080p videos down to 720p or 480p.
  3. Select a compression level. The 'Medium' setting provides a near visually-lossless experience while dropping file sizes by up to 60%.
  4. Wait for your device to crunch the video frames, then download the optimized file.

Frequently Asked Questions

Why is it taking so long?

Video compression is extremely mathematically heavy. Since this tool runs 100% locally in your browser without cloud servers, it is limited by the speed of your personal computer's CPU.

Are my files uploaded to a server?

No. The video is processed securely inside your own device using WebAssembly.
