Make small or blurry photos bigger and sharper. An AI model (Real-ESRGAN) redraws fine detail and cleans up noise and JPG artifacts, instead of just stretching the pixels.
Ordinary resizing only stretches the pixels, so the result looks soft. The AI model has learned what real edges and textures look like, and fills in sharp detail as it enlarges.
The result can be up to about 16 megapixels, for example 4096 × 4096. An image too large for 4× is enlarged 2× instead.
The AI runs on your own device. With a modern graphics card (WebGPU, in Chrome and Edge) an image takes seconds. Without one, the processor does the work, which can take a few minutes for large images.
