🔍 PDF Upscaler

Upload a scanned PDF — each page is rendered, passed through Swin2SR super-resolution tile-by-tile, and rebuilt into a sharper PDF with the same page size but higher pixel density (text comes out crisp, not blurry). Runs on ZeroGPU — pages process in seconds, subject to your daily GPU quota.
