Upscayl

Overview

GitHubGitHub

Upscayl is a free, open-source desktop app built with Electron and TypeScript that uses AI algorithms to upscale and enhance low-resolution images. ## What It Is Upscayl leverages AI models like ESRGAN to enlarge small or blurry images to higher resolutions while preserving as much detail as possible. The project is hosted on GitHub, open-sourced under the AGPL-3.0 license, and is currently at version v2.15. ## What Problem It Solves When users need low-resolution images for printing, presentations, or other high-clarity scenarios, traditional interpolation often results in blurriness. Upscayl provides a locally run AI upscaling solution, allowing image processing without relying on cloud services. ## Key Capabilities - **AI Image Upscaling**: Uses advanced AI algorithms to upscale images without quality loss. - **Cross-Platform Support**: Available for Linux (AppImage, Flatpak, Snap, AUR, DEB, RPM), macOS (DMG, Homebrew, Mac App Store), and Windows. - **Local Processing**: All computations run on your local GPU—no images are uploaded to any server. ## Hardware Requirements Upscayl requires a Vulkan-compatible GPU to perform upscaling. Many integrated GPUs (iGPUs) may not work properly, but you can still give them a try. ## Who It's For Ideal for everyday users, designers, or developers who need to upscale images locally with AI—especially those looking for a free, open-source alternative to commercial software like Topaz Gigapixel.
