Models Built for Every Source
Specialized AI pipelines — swap models in one click, render locally on your GPU.
Real-ESRGAN
Industry-standard super-resolution for photos, screenshots, and mixed content at 2×–4× scale.
Anime Upscaler
Preserves clean line art and flat color regions — ideal for anime, manga, and cel-shaded artwork.
Photo Restoration
Recovers detail in faded scans, old prints, and compressed JPEGs with balanced denoise and clarity.
Texture Enhancement
Rebuilds surface detail in tileable textures, normal maps, and game assets without muddy artifacts.
问题
低分辨率并不好玩
Blurry photo or pixel soup? Upscayl is built for exactly that.
问题
Old photos, compressed JPEGs, and tiny game textures lose detail when stretched in basic editors. Guessing settings or paying for cloud tools is slow, expensive, and risky for private work.

解决方案
Upscayl uses advanced AI to reconstruct detail: pick an image, choose a model and scale, and let your GPU do the rest. 预览 modes help you compare before you save.

Yep. Upscayl is 100% free and open source — no premium tier, no sneaky subscription. 下载 it, upscale your stuff, keep your money for snacks.
Absolutely not. Everything stays on your machine. 您r images never touch our servers — we love your privacy as much as your high-res art.
您 need a Vulkan-compatible GPU (Nvidia, AMD, or Intel Arc). Integrated graphics can work, but update your drivers first.
Please do. Batch mode lets you queue entire folders — point, click, walk away. 您r GPU does the rest.
