waifu2x.booru.pics
waifu2x.booru.pics was a free online photo upscaler that ran the waifu2x algorithm for anime-style art and photos. You uploaded an image, picked noise reduction and upscale settings, and downloaded a higher-resolution file without paying or creating an account. The site operated as a community mirror of the open-source waifu2x project from 2016 through 2024.
Unlike the official waifu2x.net generator, this mirror stayed free for eight years by absorbing GPU costs without ads or subscriptions. Operators noted their models lagged slightly behind the original project, but the service handled the same core workflow: denoise JPEG artifacts and upscale images by factors like 2x.
The operators shut the site down to repurpose their GPU server for other projects, citing rapid advances in image generation and upscaling alternatives. The homepage now points visitors to waifu2x.net or self-hosted tools like Stable Diffusion WebUI and video2x.
