Real-ESRGAN

Detail-preserving AI model

Upscale images 2× or 4× with AI

The AI Image Upscaler enlarges photos and graphics 2× or 4× using Real-ESRGAN — a model that reconstructs plausible detail instead of simply stretching pixels, so the result looks sharp rather than blurry.

It's ideal for rescuing small or low-resolution images: tiny logos, old photos, product shots, or artwork you want to print or show on a big screen. The model runs on your own GPU in the browser (falling back to CPU), so your image never leaves your device.
