ScanDeck: PDF Document Scanner

ScanDeck is a free document scanner and PDF scanner app that turns your phone into a fast, private scanner for documents, receipts, ID cards, books and notes. Point the camera at a page, and ScanDeck finds the edges, straightens it and cleans it up into a sharp, searchable PDF. Your documents stay on your phone: no account, no cloud upload.

SCAN ANYTHING
• Document, ID Card, Signature, Book, OCR Text and QR modes in one camera, so you can switch with a swipe
• Automatic edge detection and perspective correction
• ID Card mode scans the front and back onto one page at real card size, ready to print
• Book mode splits a two-page spread into separate pages
• Import photos you already took from your gallery

CLEAN, SHARP PAGES
• Auto, Color, Grayscale and Black & White filters with live previews
• Crop with four-corner handles, rotate, reorder, add or delete pages
• Edit a saved document any time

FIND IT LATER
• Text recognition (OCR) runs on your phone, so every scan becomes searchable
• Search titles and the text inside your pages, with matches highlighted
• Copy text straight from a page
• Category folders are created for you, and you can make your own
• Filter by folder, sort by date or name

SIGN, PRINT AND SHARE
• Draw your signature once and place it on any page
• Export searchable PDFs with no watermark
• Print directly from the app
• Share to email, chat or cloud drives

QR AND BARCODE SCANNER
• Read QR codes and barcodes live, or from a photo
• Open links, join Wi-Fi, call, email or text with a tap. Nothing happens until you choose.

PRIVATE BY DESIGN
• Documents, page images and recognised text never leave your phone
• Lock the app with your fingerprint, face or screen lock
• Encrypted, password-protected backup and restore to a file you control
• Trash with 30-day recovery

Works in English, Deutsch, Español, हिन्दी, 日本語, 한국어, Русский and 中文, with light and dark themes.

ScanDeck is free. It shows a small banner in the Library and Settings, never while you scan, and never a full-screen ad.
