Turn low-resolution images into sharp, high-quality photos

Upscayl uses AI to intelligently enlarge images — adding realistic detail rather than just stretching pixels. It works great on old photos, low-res downloads, game screenshots, and AI-generated images. Everything runs on your computer, so your images stay private.

FAQ

How much can Upscayl enlarge an image? 4x is the standard setting (e.g., 500x500 becomes 2000x2000). Some models can go up to 16x. Multiple passes are also possible for even larger results.

Which AI model should I choose? Real-ESRGAN is best for photos and real-world images. RemaCRI works better for illustrations, anime, and digital art. Try both on a sample to see which gives better results for your specific image.

Does Upscayl work on old scanned photos? Yes. In fact, old photos are where upscaling is most dramatic. The AI can add plausible detail to blurry areas and reduce noise in scanned images.

Is there a file size or daily limit? None. Upscayl is completely free and unlimited. Process as many images as you want with no watermarks or restrictions.
