VideoDownsizer

Shrink videos to a fraction of their size — right on your iPhone and iPad. VideoDownsizer re-encodes your videos with the hardware encoder built into your device, so a clip that was too big to send becomes easy to share. Everything happens on-device: nothing is uploaded, nothing is queued, and no data plan is used. WHY YOU WILL LIKE IT • Files 60–80% smaller, with the same frame rate and orientation as the original • Four compression levels and four resolutions — from "keep it sharp" to "make it tiny" • Hardware H.264 encoding, or HEVC when you need the smallest possible file • Audio is passed through untouched and never re-encoded • See the estimate before you commit: the confirm screen puts the original next to the expected result • Three-stage progress (read / decode / encode), pausable and cancellable at any time • Lock the screen and it pauses; come back and it continues where it left off • Universal app for iPhone and iPad, in English, Simplified Chinese and Spanish PRIVACY No account, no analytics, no ads and no servers. The app makes no network requests at all. Your original video is never modified — a new file is always written. FORMATS Input: MOV, MP4, M4V and other common video files, including HEVC. Output: MP4. HOW TO USE 1. Tap "Choose from Photos" or "Choose from Files". 2. Check the confirm screen: resolution, settings and the estimated file size. 3. Tap "Start compressing" and wait for the three stages to finish. 4. Save the result to Photos, or use "Save to Files".
