AI Image Upscaler

Enlarge a photo 4x using real AI super-resolution (Real-ESRGAN), not just a simple stretch.

Works best on photos. Runs on CPU, so it can take up to a minute or two — larger uploads are automatically downscaled first to keep that bounded. Not recommended for images with text, logos, or sharp graphics (the model can distort fine detail).
