Upscayl is a free and open-source AI-powered image upscaling tool designed to increase the resolution of images while preserving and enhancing details. It utilizes advanced AI models to intelligently upscale low-resolution photos, digital art, and screenshots by up to 4x or more, reducing pixelation and blurriness. The application runs entirely offline on your local machine, ensuring user privacy and security as no data is sent to external servers.

Its key features include a simple drag-and-drop interface, support for batch processing multiple images, and the ability to choose from different AI models optimized for various image types like photos or illustrations. It is built for users who need high-quality image enlargement without watermarks, subscriptions, or privacy concerns. Upscayl is particularly popular among photographers, digital artists, archivists, and general users looking to enhance old photos or improve image quality for printing or digital use.
