Compress a video to a smaller file

File size is bitrate × duration. Pick a lower bitrate, or a smaller resolution, and export H.264 MP4. Because nothing is uploaded, there's no file-size limit on the input.

Compress a video No sign-up. Files never leave your device.

How to compress a video

  1. Click Compress a video, import your file and drag it to a new sequence.
  2. Press Ctrl/Cmd+M (File › Export › Export) to open the Export page and choose H.264 in an MP4.
  3. Pick a lower resolution (e.g. 1280×720) and a target bitrate; 2–4 Mbps is plenty for 720p.
  4. Export and check the size; to hit a size exactly, use target MB × 8 ÷ seconds = Mbps.

Tips

  • For Discord's 10 MB limit and a 60-second clip: 10 × 8 ÷ 60 ≈ 1.3 Mbps total, so set the video to about 1.1 Mbps and the audio to 128 kbps.
