Upscayl – Free and open-source AI image upscaler

In the past, when we encountered some particularly poor-quality, small-resolution or blurry pictures and wanted to make them larger and clearer, our first thought was to use tools such as Adobe Photoshop and GIMP to enlarge and sharpen the image. But the results are mostly unsatisfactory. Because the enlarged image is either full of mosaics or blurred, or loses a lot of details. Now, the development of AI technology is also revolutionizing the image processing technology.
