Scan, convert and protect your documents, right on your iPhone. No ads. No watermarks. No sign-in. No scan limit. EASY - SMART SCAN - Auto-capture: hold your phone over a page; the app finds the edges and takes the shot. Prefer to tap the shutter yourself? Switch to manual capture anytime. - Auto-align: perspective is corrected and the page is cropped for you, then your default filter is applied (Magic Color unless you choose another in Settings). - Six filters: Original, Magic Color, Black & White, Grayscale, Sharpen and Denoise, for one page or every page at once. - Rotate pages, import from Photos or Files, and share through the iOS share sheet: Mail, messaging apps or Save to Files. EFFICIENT - ADVANCED OCR - On-device text recognition with Apple Vision, in English, Vietnamese, Japanese and Chinese. - Extract text from the camera, your photo library or a PDF. - PDF to Word keeps tables and math formulas as editable content. - Content search: find words inside your documents, not just in file names. Search runs on your device. EFFICIENT - PDF TOOLKIT - 13 tools: merge, split, reorder, rotate, compress, watermark, lock, unlock, images to PDF, Word to PDF, PDF to Word, extract text and ID card (front and back on one A4 page). - Sign: draw your signature or pick it from a photo, then place it on any page of a PDF. - Blur: hide account numbers, addresses or faces on a page and save the result as a new document. - Open Word files inside the app, and print wirelessly. ENCRYPTED - YOUR DOCUMENTS STAY YOURS - Contracts, bank statements, ID cards: scans, PDFs and document names are encrypted with AES-256 where they are stored, on your device. - Files use iOS data protection and are excluded from iCloud and device backups. - Lock the app with Face ID or a PIN, and put a password on important PDFs. - Scanning, editing, search and export all work offline. CLEAR ABOUT THE CLOUD Server processing is off by default. Only three tools use it: PDF to Word, Extract text from a PDF, and Word to PDF. They stay off until you turn on Advanced OCR in Settings and accept the data notice. Everything else runs on your device. PREMIUM The free version is complete: no ads, no watermarks, unlimited scanning and every tool. Premium adds: - Advanced OCR: 150 pages a month (up to 30 a day) instead of 10 a month - Merge PDF: unlimited files instead of 3 at a time - Images to PDF: unlimited images instead of 5 per PDF - Word to PDF: unlimited instead of 20 a day - Blur: unlimited instead of 10 free uses - Content search: free users see which documents and pages match; Premium opens a result at the matching page, shows snippets, and searches inside scanned documents - Lock and unlock PDFs with a password SUBSCRIPTION INFORMATION e-Scanner Premium is an auto-renewing subscription, monthly or yearly. The price in your currency is shown in the app before you buy. Payment is charged to your Apple Account at confirmation of purchase.
