Waifu2x

Waifu2x is an AI-powered image enhancement tool designed for high-quality upscaling and noise reduction, with particular strength in anime-style artwork and illustrations. Using deep convolutional neural networks, it enlarges images while preserving clean line work, color gradients, and fine details that are often lost with traditional scaling methods. In addition to anime art, Waifu2x supports photographs, making it useful for a broad range of visual content.

Core capabilities include single-image super-resolution (commonly 2x upscaling) and adjustable noise reduction levels to remove compression artifacts and grain without excessively blurring the image. The web-based interface allows users to upload images directly, select noise reduction intensity, choose the upscaling factor, and process files without installing local software.
