CleanScan: PDF Scanner

CleanScan turns your iPhone into the cleanest document scanner — and it works 100% offline. Nothing is uploaded. No account. No sign-in. WHY CLEANSCAN • Shadow removal — flat-field correction erases the shadow your hand casts, so the whole page is evenly lit. • Auto-straighten — edges are detected and the page is de-skewed to a clean rectangle. • Crisp black & white — an adaptive threshold keeps small text sharp while making the background pure white. Color and Grayscale modes too. • Uniform A4 PDFs — mixed page sizes come out as tidy, consistent pages. PRIVATE BY DESIGN • 100% on-device processing. Your scans never leave your iPhone. • No account, no servers, no document upload — ever. • A document only leaves your device when you choose to share or email it. EVERYDAY SCANNING • Multi-page documents — scan, reorder by drag, rename, add or remove pages. • Export to PDF and share via Mail, Messages, Files, or AirDrop. • Offline history of everything you've scanned, stored only on your device. • Available in English, 繁體中文, 简体中文, Español, 日本語, Português, Deutsch, Français. CleanScan is free and supported by ads.
