What is waifu2x.booru.pics?

Waifu2x.booru.pics is a free web-based image upscaler designed specifically for anime, manga, and illustrated artwork. It enlarges images up to double their original size while reducing noise and compression artifacts, keeping the distinctive style and detail of drawn art intact. The tool works through a simple upload or URL submission process and lets you adjust noise reduction intensity and choose between two processing modes: Art (for illustrations) or Photo (for photographs).
