Scan PDF: Document Scan & OCR turns your phone into a powerful document scanner. Everything runs on your device, and it works offline. SCAN ANYTHING Automatic edge detection and perspective correction give you sharp, flat scans of documents, receipts, ID cards, whiteboards and notes. Auto / Grey / Black-and-white filters plus a brightness slider make every page as clean and readable as print. MAKE A PDF INSTANTLY Export multi-page PDFs (A4 / Letter / fit-to-image), tune compression to keep files small, then share to Gmail, Drive, Messages — or print directly. Lock a PDF with AES-256 encryption. Add your own watermark, timestamp and footer (name + logo). OCR — EXTRACT AND SEARCH On-device OCR pulls editable text out of your scans, in Latin scripts plus Chinese, Japanese, Korean and Hindi. Copy it, share it, or search your whole library by what is written inside your documents. On export, keep the photo and add an invisible searchable text layer, or rebuild the page as selectable vector text — razor sharp at any zoom and remarkably small. SCAN QR CODES AND BARCODES Read QR codes and barcodes on device; open links straight from the result. MERGE, SIGN AND ORGANISE Combine several PDFs and images into one file. Sign and annotate by hand, reorder pages, rotate, delete the ones you do not need, and export any page to your photo library as JPG or PNG. Keep everything tidy in folders with instant search. YOUR DATA STAYS ON YOUR PHONE Every scan, OCR pass and PDF is processed on your device and never uploaded to our servers — no account, no cloud sync, works in airplane mode. Lock the app with a PIN or Face ID / Touch ID, and protect any PDF with AES-256. Available in 17 languages, including English, Tiếng Việt, 简体中文, 日本語, 한국어, Español, Português, Bahasa Indonesia, हिन्दी, العربية and more. The free version is ad-supported; our advertising partners may use your device identifier. Download Scan PDF: Document Scan & OCR — a simple, private scanner that just works.
