Upscayl is an AI-powered image upscaler that is free, open source and available on Linux, macOS and Windows. It can scale up small, low-resolution pictures and improve their detail with AI models, aiming to avoid the usual loss in quality. It is built with TypeScript and Electron and released under the AGPL-3.0 license.
The README provides installation instructions for each operating system, plus tutorials and guides, before-and-after demo results, a roadmap and an FAQ. A Vulkan-compatible graphics card is required for upscaling, and the project notes that many integrated GPUs do not work. Topics reference ESRGAN-based upscaling models.
The app runs locally on your own computer, so images are not sent to an online service. It suits photographers, designers, game modders and anyone restoring old or small pictures who wants a free alternative to paid upscaling software.
