How to resize a video

  1. Drop your video in. Choose or drag an MP4, MOV or WebM — it loads in your browser and is never uploaded.
  2. Pick a target height. Choose 1080p, 720p, 480p or 360p; the width follows the aspect ratio and the new size is shown.
  3. Resize & download. The scaled video is re-encoded to MP4 on your device and downloaded, with audio kept.
