Upscayl

Upscayl is a free, open-source AI image upscaling application designed for Linux, macOS, and Windows that enhances low-resolution images using advanced deep learning models. The tool focuses on converting small or compressed images into higher-resolution versions while preserving detail and minimizing artifacts. Users can upscale images by 2x, 4x, or more, depending on the selected model and configuration. Upscayl supports various image formats and offers batch processing, allowing multiple images to be upscaled in a single operation, which is useful for large photo collections, design assets, or game textures.

The application provides several AI models optimized for different content types, such as photographs, digital art, and anime-style images, enabling users to choose the most appropriate model for their source material. Its interface is straightforward, with options to preview results and customize output settings like scale factor and output directory. Common use cases include restoring old or low-quality photos, improving assets for web and print design, refining textures for game development, and enhancing images for presentations or social media. Because Upscayl runs locally, it does not require uploading images to a remote server, offering better control over privacy and performance.
