Waifu2x
Free browser-based tool that upscales and denoises anime artwork and photos using deep convolutional neural networks.
About
Waifu2x originated as an open-source project for super-resolution of anime-style art and has become a widely used free utility for anyone needing quick upscaling without installing software. You upload an image and choose a noise-reduction level and a magnification factor of 1.6x, 2x, or 4x, and the tool returns a cleaned, enlarged version.
It handles both anime artwork and photographs through separate processing models. The free version imposes size limits, capping input images at 5 MB and noise reduction at 3000x3000 pixels. An unlimited tier is available separately for users who need to process larger files.
The service runs in the browser with no signup required, making it accessible to anime fans, manga artists, and anyone wanting a fast no-cost upscaler.
