Images look blurry on a 4K/HiDPI screen over 100% display scaling, or on Retina? The browser upscales them with a cheap bilinear filter. This resamples them with a real Lanczos3 filter on the GPU instead. No third-party requests; nothing leaves your browser. Built for manga, comics, and webtoons, works anywhere.
