Meet iScanner—the AI-powered document scanner trusted by 145M+ users to scan, edit, and manage files. Students, professionals, remote workers, teachers. For many, important documents still exist on paper when they should be digital. Built on 10+ years of scanning experience, iScanner solves that. Just point your camera at a contract, a receipt, or a handwritten note and get a clean file back. With iScanner, you can: • Scan documents to PDF, JPG, DOC, or other formats with automatic quality correction. • Sign PDFs, fill out forms, and annotate documents without switching apps. • Extract text from any scan using built-in OCR in 20+ languages. Here's what you get: AI-POWERED DOCUMENT SCANNER Got a crumpled receipt or a contract shot at an angle? iScanner's in-house AI automatically detects borders, straightens skewed pages, corrects colors, and removes shadows, fingerprints, and noise. The result looks like it was produced by a flatbed scanner. Export as PDF, JPG, DOC, XLS, PPT, or TXT. ALL-IN-ONE DOCUMENT EDITOR Unlike most scanner apps that stop at the scan, iScanner handles every step of document management. Sign by hand or from a photo, fill out forms, annotate pages, and redact sensitive text. Merge several scans into one file, split pages, send a fax, and organize them into folders with drag and drop. OCR & AI PDF ASSISTANT Built-in OCR turns printed text into editable content in 20+ languages—copy it, convert the scan to a DOC or TXT file, or search any PDF. Got a dense contract or a document in a foreign language? AI Chat can summarize, translate, rewrite, or answer specific questions about it. PRIVACY & DOCUMENT SECURITY Passports, medical records, financial documents. Some files belong on your device, not a shared cloud. iScanner keeps them there by default, with no third-party access. Lock the app with a PIN, Face ID, or Touch ID. Password-protect PDFs, set expiration dates on shared links, and add a decoy password that opens a fake version of the app. SPECIALIZED SCANNING MODES Beyond everyday documents: create secure digital copies of passports, ID cards, and driver's licenses. Photograph a math equation and solve it instantly. Measure object dimensions, count similar objects, and read QR codes—all in one app. CROSS-DEVICE ACCESS Files sync through secure AWS cloud storage and are available to manage from any browser using the web version. Import from Gmail, Google Drive, and Apple Files. PAPERLESS IMPACT Since 2015, iScanner has helped millions of people replace printouts with digital files. Track your real environmental impact inside the app and earn eco certificates for going paperless. Download iScanner—the AI-powered document scanner that handles everything from the first scan to the final signature. FAQ Q: Can I scan multiple pages into one PDF? A: Yes—scan as many pages as you need and combine them into a single file. Q: Does iScanner work without an internet connection? A: Yes—scanning, editing, and viewing files all work offline; only cloud sync and backups need a connection. Q: How do I transfer my documents to a new phone? A: Sign in on your new device and everything restores automatically from iScanner's cloud storage.

Verdict

The call

The clearest difference is ads: Scan to PDF at none against iScanner's shown. Scan to PDF also leads on iOS requirement (16.0 vs 18.0). iScanner's advantage is review sentiment (82% vs 48%) and ratings volume (1.4M vs 24K). On price, rating, in-app purchases and monetization model there is nothing between them.
