RePix - AI Image Upscaler

RePix enlarges your photos with AI — right on your iPhone. Blurry screenshots, old photos, compressed images saved from social media: RePix uses an AI super-resolution model to upscale them 2x or 4x, producing sharp edges and clean detail instead of simply stretching pixels. YOUR PHOTOS NEVER LEAVE YOUR DEVICE All processing happens on your iPhone. Your images are never uploaded to any server. No account or sign-in required. FEATURES - AI upscaling at 2x or 4x - Crop freely or with preset aspect ratios, and rotate - Before/after comparison slider - Save as JPEG or PNG, or share directly to other apps FREE TO USE Enjoy one free 2x enhancement every 24 hours.

If an area is too large, crop it to the size shown in the app first.
