Overview
Upscayl — Free open-source AI image upscaler for macOS, Windows, and Linux using ESRGAN models.
Upscayl is a free, open-source AI image upscaling application for desktop that uses state-of-the-art ESRGAN models to enlarge images up to 4x while enhancing detail and sharpness. Unlike simple interpolation, Upscayl's AI generates realistic texture details, making it useful for restoring old photos, enlarging artwork, and improving low-resolution screenshots. It runs entirely on the local device, preserving privacy and working offline. Upscayl is used by photographers, designers, digital artists, and anyone who needs to upscale images for print or high-resolution display without cloud dependency or subscription costs.
