📝 About Upscayl
Upscayl makes AI upscaling something anyone can do for free. The cross-platform desktop app takes blurry, low-resolution images and enlarges them two, four, or eight times using Real-ESRGAN models, with Vulkan GPU acceleration doing the work locally. Nothing is uploaded, so private photos stay private.
Multiple built-in models suit different content, from photos to artwork to text-heavy scans, custom models can be added, and batch mode processes entire folders. An optional cloud service handles jobs on machines without a capable GPU.
Results depend on the source material; badly compressed images can develop artifacts, and choosing between models takes some experimentation. But for restoring old family photos, improving game assets, or prepping images for print, Upscayl is the most accessible upscaler of 2026 at the best possible price.
