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.

Scanner turns paper into clean, professional PDFs in seconds — and the core scanner is genuinely free. No subscription. No watermark on your exports. No account to create. No trial that expires halfway through your first scan. NO PAYWALL, NO CATCHES Most scanner apps let you scan, then ask for money at the moment you try to export. This one doesn't. Scanning, multi-page documents, PDF creation, sharing, filters, cropping, text recognition and search are all free, with no page limits. SCAN ANYTHING, INSTANTLY Point your camera at a document and Scanner finds the edges, straightens the perspective and crops it automatically. Receipts, contracts, notes, business cards, whiteboards, ID cards, forms, handwritten pages — if it's on paper, it scans. A CAMERA SCANNER, NOT A PHOTO ALBUM Your camera takes a picture of a page. Scanner turns it into a document — edges found, perspective straightened, shadows removed, paper made white. Already have photos of documents? Import them and the same thing happens: each page is detected, cleaned up and combined into one properly sized PDF. Photos to PDF, receipts to PDF, whole stacks of paper to PDF, all on device. MANY PAGES, ONE DOCUMENT Keep scanning and pages stack into a single document. Drag to reorder, rotate, crop, duplicate or delete any page, and add more later. Export the whole thing as one file. REAL PDFs, NO WATERMARK Exported PDFs are sharp, properly sized and completely unbranded. Choose Standard for smaller files that email easily, or High Quality when detail matters. Share straight to Messages, Mail, AirDrop, Files, or any app on your device — or save individual pages as JPEG or PNG. SEARCHABLE TEXT, INCLUDED Scanner reads the text on your pages using your device's built-in recognition, so you can search your scans by their contents. Look for "insurance" and find the insurance document, even if that word isn't in the title. Your exported PDFs are searchable too. Text stays selectable and findable in Files, Preview, Acrobat and Gmail — not just inside this app. Most apps charge for that. This one doesn't. CLEAN UP EVERY PAGE Enhanced mode evens out shadows and uneven lighting so text is crisp and paper looks white. Or pick Color, Grayscale, or high-contrast Black & White. Adjust the corners by hand whenever you like — your original capture is always kept, so nothing is ever destroyed. STAY ORGANIZED Sort scans into folders, star the ones you need often, rename anything, and switch between list and grid. Deleted something by accident? Recently Deleted holds it for 30 days. YOUR DOCUMENTS STAY ON YOUR DEVICE This is the part we care about most. Your scans never leave your phone. They aren't uploaded to us, sent to an AI service, or used for advertising. Text recognition runs entirely on device. There's no account because there's nothing to sync — and nothing for anyone to breach. Scanning works fully offline. WHY PEOPLE SWITCH It's a free iPhone scanner that behaves like a paid one: fast, quiet, native, and honest about what it does. No fake AI branding, no onboarding survey, no popup asking you to subscribe before you've scanned a thing. Scanner is supported by ads, kept deliberately away from your documents. You will never see an ad while the camera is open, while you're cropping or editing, while text is being recognized, while a document is on screen, or inside an exported PDF. Also works on iPad.

Verdict
The clearest difference is in-app purchases: Doc Scanner To PDF at none against Scanner PDF's 1. Doc Scanner To PDF also leads on ads (none vs shown). Scanner PDF's advantage is iOS requirement (15.5 vs 17.0). On price and device support there is nothing between them.
