Upscayl is a versatile application that seamlessly operates on multiple platforms. That said, Upscayl is a niche tool, as you will need a dedicated GPU with Vulkan support.

With Upscayl, you can easily upscale your images without any prior knowledge of doing so. The program quickly starts working on your photo once you upload it. It supports camera stills and digital artwork, making it compatible with a wide range of content.

Upscayl utilizes advanced artificial intelligence algorithms to enhance the clarity and sharpness of your images. There are two types of upscaling - one for general photos and one specifically for digital art. Selecting the appropriate kind of upscaling that matches your photo is essential to achieve optimal results. Upscayl doesn't provide specific details about their upscaling methods, but they boast that their AI-powered assistant will significantly improve the quality of your images.

Although Upscayl is available for Windows and macOS, the app is designed with a Linux-first approach.
