RePix - AI Image Upscaler

Upscale photos 2x or 4x with on-device AI. Your images never leave your iPhone — no upload, no account.

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.
