About PDF Document Scanner
PDF Document Scanner turns your phone camera into a portable document scanner. Point your camera at any document — receipts, contracts, notes, whiteboards — and it automatically detects the edges and corrects the perspective so every page comes out flat and straight. Export a clean PDF in seconds.
Add as many pages as you want, rearrange or delete individual pages, then export the whole document as a standard PDF saved directly to your Downloads folder. Everything — edge detection, perspective correction, and PDF rendering — runs locally using pure Kotlin. No documents are ever sent to a server.
