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.

At present, various desktop and online applications based on AI technology, cloud computing, and machine learning emerge in endlessly. Among them, algorithms such as Real-ESRGAN, Real-CUGAN, and SRCNN can nearly losslessly enlarge images (different models are suitable for different types of pictures, such as figures, landscapes, animations, wallpapers, design drafts, etc.), the effect is amazing. Thereinto, Real-ESRGAN is a well-known super-resolution technology based on deep learning, which can increase the resolution of pictures by 4 to 8 times while maintaining the details and textures of pictures. It can handle not only ordinary RGB images, but also special types of images such as transparency, normal maps, and anime styles.

Upscayl is a free, open-source image lossless magnification (clearing) tool for Windows, Mac and Linux platforms, based on open-source, super-resolution algorithm models. It has built-in Real-ESRGAN and several other popular AI models that can be switched at will. It is easy to use, supports batch processing and command line operation, and can quickly zoom in on images with amazing results. By using advanced AI models, Upscayl can upscale low-resolution images, making blurry pictures clearer as they are zoomed in.

The AI ​​model enlarges and enhances the image by guessing and complementing the missing details of the low-resolution image, thereby repairing the deficiencies of the original image and making the enlarged image clearer and richer in detail. So, whether it’s blurry old photos, pictures from Internet or low-resolution game screenshots, Upscayl can help you enhance/fix the quality of your pictures, making them look clearer, more detailed and more realistic. In short, if you need to enlarge pictures and repair blurred photos, remember to give Upscayl a try.
