About
Upscayl is a powerful, free, and open-source AI image upscaling application designed for creators, designers, artists, businesses, and developers. It leverages cutting-edge AI models to enhance image resolution by up to 16x, turning pixelated or blurry photos into sharp, detailed works of art — all without expensive software subscriptions. The desktop app runs natively on Linux, macOS, and Windows, offering a privacy-friendly local processing experience. Users can choose from multiple AI models tailored to different image styles and use cases, batch-upscale entire folders of images at once, and even apply double upscaling for maximum quality gains. Extensive customization options let users fine-tune output to match their specific needs. Upscayl Cloud extends these capabilities to the browser, enabling upscaling on desktop, mobile, and tablet devices without installing anything. The cloud tier boasts 10x faster processing, improved color accuracy for print-ready results, multiple model styles, unlimited cloud storage, and support for very large resolutions. Whether you're restoring old family photos, preparing assets for print, enhancing game textures, or cleaning up product images for e-commerce, Upscayl provides a professional-grade result that rivals expensive paid alternatives — completely free for the desktop experience.
