Upscayl is our favorite cross-platform image upscaling tool, and it's free

Upscayl is a highly effective image upscaling tool that utilizes sophisticated AI technology to enhance and enlarge images without compromising quality. This innovative software employs Real-ESRGAN and Vulkan architecture to produce remarkable results. The entire backend of Upscayl is fully open-source and licensed under AGPLv3, providing users with complete transparency and control.

However, it's important to note that using Upscayl requires a Vulkan-compatible graphics card. Currently, CPU-only mode is not supported, and many integrated graphics processors (iGPUs) may not be compatible. Upscayl Desktop, available for Linux, MacOS, and Windows, offers the same core functionality as the original software, ensuring a seamless user experience across various platforms.

While Upscayl Desktop is completely free and open-source, the version available on the Mac App Store is distributed under Apple's licensing rules. Paid users of the Mac App Store version enjoy additional benefits, including priority email support, automatic updates, and access to more AI models that are still in development.

The beauty of Upscayl lies in its limitless potential. Users can upscale as many images and in as many formats as they desire. All processing occurs locally on the user's machine, eliminating the need for an internet connection. This means that Upscayl Desktop provides access to several AI models, enabling enhanced quality and performance.

One of the standout features of Upscayl Desktop is its flexibility. Users can customize the software to suit their preferences, adjusting the theme, model, and output resolution. This level of control empowers users to tailor the upscaling experience to their specific needs. With Upscayl Desktop, the power is truly in the hands of the user, allowing for a personalized and efficient image upscaling process.
