Upscayl — upscale and enhance image resolution

Upscayl is an open-source AI image upscaler for increasing photo resolution and quality locally on your desktop

Upscayl is an open-source tool that allows users to increase the resolution of low-quality images using deep learning models. This desktop software is built for business owners, photographers, and marketers who need to prepare low-resolution assets for print, high-definition displays, or professional presentations. Unlike web-based tools that compress files, Upscayl performs processing locally on your computer to ensure maximum privacy and data security. The software offers multiple AI models tailored to different types of visuals, including digital art, photographs, and scanned documents. Business users can take advantage of the batch processing feature to upscale dozens of product photos or marketing assets simultaneously. You can find detailed technical comparisons of these models on surfai.app to determine which setting fits your specific project needs. Upscayl supports a wide variety of output formats and allows for sharp detail retention even when enlarging images by 400%. Because the tool runs on your local hardware, there are no monthly subscription fees or upload limits often found in competing cloud services. This makes it a reliable asset for creative teams managing high volumes of visual content. As of 2026, Upscayl remains free to download and use on MacOS, Windows, and Linux. The project is supported by community donations and offers a cloud-based version for users who prefer not to use their own hardware resources.
