Upscayl lets you enlarge and enhance low-resolution images using advanced AI algorithms.

Upscayl is a powerful image upscaling tool that uses advanced AI technology to enhance your images. It allows you to enlarge images without losing quality. It's almost like magic!

Upscayl uses Real-ESRGAN and Vulkan architecture to achieve this. Our backend is fully open-source under the AGPLv3 license.

Do I need a GPU to use Upscayl Desktop?

Yes, you need a Vulkan-compatible graphics card to use Upscayl. CPU only mode is not supported at the moment and many iGPUs are not supported.

Why is the Mac App Store version of Upscayl not free, while the desktop version is?

Upscayl Desktop is licensed under the AGPLv3 and offers the same core functionality. However, the version available on the Mac App Store is distributed under Apple's licensing rules and includes additional features for paid users-such as priority email support, automatic updates, and access to additional AI models (currently in development).
