Upscayl

Overview

Upscayl is a free and open-source Artificial Intelligence (AI) image upscaler developed with a strong emphasis on Linux compatibility, yet it is also cross-platform, supporting MacOS and Windows. Created by TGS963 and Nayam Amarshe, Upscayl utilizes advanced AI algorithms, specifically Real-ESRGAN, to upscale low-resolution images, enhancing them without significant quality loss. The tool fills in missing pixels during upscaling, ensuring high-quality output images. It requires a Vulkan-compatible Graphics Processing Unit (GPU) for operation, although attempts to use it with other CPUs or integrated GPUs should not cause harm. Being open-source under the GNU Affero General Public License v3.0, Upscayl invites community contributions to its development​​​​.
