- Select a Model based on the image you are upscaling. There are six AI upscale models available on the Upscayl program. Each model makes a little difference in the upscaled images. The General Photo (Real-ESRGAN) model is a common model that can upscale all kinds of images. If you are new to upscaling images, this model is good. The General Photo (Fast Real-ESRGAN) model is good if you prioritize speed over image quality. If your image has more details and colors that you need to preserve while upscaling, selecting the General Photo (Remacri) model is ideal as it preserves details and colors in the image. If you want to upscale your images speedily and without losing the quality, you need to select General Photo (Ultramix Balanced). To make the images look sharp after the upscaling, the General Photo (Ultrasharp) model will help. The Digital Art model is more suitable to upscale digital art and illustrations than other models.
- After selecting the upscaling model, you need to slide the Image Scale bar to get the desired size like 2x, 4x, etc.
- Then, select the output folder by clicking on the Set Output Folder button.
- Now, click on Upscayl and wait for the upscaling process to be completed. It depends on your system configuration, image models, quality, and the number of images you have selected to upscale. After the process is completed, the images are automatically saved in the output folder.
