Private, on-device compression
Comprimo shrinks videos using your iPhone's built-in video hardware. Nothing is uploaded: no account, no servers, no data collected, no ads and no tracking.
See the size first
Pick one of three presets, Keep it sharp, Good for sharing or Smallest file, and see the estimated size and the space you'll save before you start.
Every option when you need it
Choose resolution up to 4K, 30 or 60 fps, HEVC, H.264 or ProRes, MOV, MP4 or M4V, and whether to keep or strip the date and location.
Keeps HDR and Spatial Audio
Built for iPhone 4K, 60 fps, HDR and Spatial Audio recordings. Keep HDR and every audio track, or convert to SDR and stereo for sharing.
From Photos or Files
Import from Photos or Files, or drag a video onto the app. Save the copy back to either, delete the original if you want the space back, and keep a running total of what you've saved.
Try it free, pay once
Your first compression is free. After that, one in-app purchase unlocks unlimited compressions. No subscription, nothing to cancel, and Restore Purchases works on all your devices.
