Free and Open Source AI Image Upscaler.

• How does Upscayl work?
  • Upscayl uses AI models to enhance your images by guessing what the details could be. It uses Real-ESRGAN (and more in the future) model to achieve this.
• Is there a CLI available?
  • The CLI tool is called real-esrgan-ncnn-vulkan and it’s available on the Real-ESRGAN repository.
• Do I need a GPU for this to work?
  • Yes, unfortunately. NCNN Vulkan requires a Vulkan compatible GPU. Upscayl won’t work on most iGPUs or CPUs.
