PxScanner is a free document scanner and PDF toolkit for phones and tablets. It detects page edges, corrects perspective, and cleans up scans, then lets you merge, split, compress, reorder, mark up, and sign PDFs, convert Word, Excel, and PowerPoint files to PDF, and export pages as images. Everything runs on the device: no accounts, no servers, and documents are never uploaded.
