Waifu2x is an online image processing tool that uses artificial intelligence (AI) to enhance photos and other images. It uses deep learning algorithms to upscale and denoise images, transforming low-resolution images into high-resolution ones. Waifu2x takes a source image and applies a neural network to it, which uses a variety of techniques to retain the detail and texture of the original image while enhancing its resolution. This can be used to resize images for higher resolution displays, or to improve the quality of low-resolution photos. Waifu2x can also be used to reduce the noise and graininess in images, making them look smoother and more natural.
Discontinued The official website is not available but the application is still available through the download sites.
