RePix - AI Image Upscaler

RePix is an offline AI photo enhancer and image upscaler. It sharpens and enlarges your photos using Real-ESRGAN, a neural network that reconstructs detail instead of simply stretching pixels. Increase image resolution, fix blurry pictures, and improve photo quality without uploading anything. Everything happens on your device. The AI model ships inside the app. Your photos are never uploaded, never sent to a server, and never stored anywhere outside your phone. There is no account to create and no sign-in. The only network traffic RePix makes is for loading ads, and even that only starts once an ad is actually needed. WHAT IT DOES - 2x and 4x image upscaling powered by Real-ESRGAN - AI photo enhancement that recovers detail in blurry and low-resolution images - GPU-accelerated inference via Vulkan, with an automatic fallback for devices without support - Crop before you enlarge, so you can focus on the part that matters - Side-by-side comparison of the original and the result - Save to your photo library or share directly to other apps - Export as JPEG or PNG GOOD FOR - Old photos and scanned pictures that look soft or low-resolution - Blurry images you want to sharpen and clean up - Screenshots and images saved from messaging apps - Small product or profile pictures you want to print or post - Anime art, illustrations and digital drawings that need a larger canvas - Wallpapers and background images that look pixelated on a bigger screen - Photos you want to enlarge for printing without losing quality WHY OFFLINE MATTERS Most AI upscalers send your images to a cloud server. RePix does not. The entire upscaling process runs locally on your phone, which means your photos stay private, the app works without an internet connection for processing, and there is no waiting in a server queue. HOW PRICING WORKS RePix is free. One 2x upscale is available every 24 hours at no cost. Beyond that, watching a short rewarded video unlocks a single 2x run. Each 4x run is unlocked by watching a rewarded video. There are no subscriptions and no in-app purchases. PRIVACY BY DESIGN Output images are re-encoded from raw pixels, which means EXIF and GPS data from the original are not carried over. RePix stores nothing about you: the only thing saved on your device is a timestamp marking when you last used your free run. REQUIREMENTS Input images must be at least 128 pixels on the shorter side for 2x, or 256 pixels for 4x. Output is capped at 4096 pixels on the long side.
