Your biggest photos are eating your storage.
Downsize finds the photos and videos taking up the most space and shrinks them — right on your iPhone. Nothing is uploaded. Your originals are never modified.
Free with 5 conversions a day. Pro is a one-time purchase — no subscription.
How it works
Largest first
Your library, sorted biggest to smallest, so the real space hogs are at the top.
Shrink in batches
Select what you want — or drag to select a whole range — and process it in one pass.
Real controls
HEIC or JPEG, HEVC or H.264, resolution, quality, frame rate and audio. HDR stays HDR.
See the difference
Compare before and after side by side or with a slider, and pinch to inspect the detail.
Originals untouched
Downsize saves a smaller copy. Deleting anything is always a separate, explicit choice.
Private by design
Processing runs entirely on device. No account, no uploads, no ad tracking.
Nothing leaves your iPhone
Scanning, measuring, compressing, converting and comparing all run locally using Apple's own frameworks. We never see your media — we couldn't if we wanted to. Read the full privacy policy.
