ScanLens
iPhone document & PDF scanner
ScanLens is a free document scanner for iPhone. The camera finds page edges, corrects perspective, and exports a multi-page PDF with on-device OCR in 50+ languages. No account required. Works offline.
How it works
ScanLens locks the frame and fires the shutter the instant the page is steady.
Perspective corrected, shadows removed, contrast boosted. Looks like a flatbed scan — not a phone photo.
PDF or JPEG. AirDrop, Mail, WhatsApp, Files, print. Multi-page in a single file.
Capture modes
Privacy
ScanLens uses Apple's on-device Vision framework for every scan, every OCR pass, every edit. Nothing is uploaded. There is no cloud to leak because there is no cloud.
About ScanLens
ScanLens is a document scanner application for iPhone. The app uses Apple's on-device Vision framework to detect document edges, correct perspective, enhance contrast, and extract text via OCR in 50+ languages — including English, Spanish, French, German, Chinese, Japanese, Korean, Russian, Arabic, and Hebrew. All scanning, OCR, and editing run locally on the iPhone; documents never leave the device unless the user explicitly exports them to iCloud, Google Drive, Dropbox, or another destination. ScanLens supports multi-page PDF capture, batch scanning, e-signatures, AES-256 password protection, ID and passport scanning modes, and full-text search across saved documents. The app is free to download from the App Store. Premium is available at $4.99/week (3-day trial), $9.99/month (7-day trial), $29.99/year (75% savings versus monthly billing, 7-day trial), or as a $59.99 one-time Lifetime purchase that includes every future update.
FAQ
Open ScanLens, point your camera at the document, and let the app detect edges, clean up perspective, and save the result as a shareable PDF.
Yes. ScanLens uses on-device OCR to recognise and extract text from scanned documents in 50+ languages, including many handwritten notes.
Yes. ScanLens lets you place a reusable signature on any PDF directly on your iPhone. Electronic signatures are legally binding under the ESIGN Act (US), UETA, and eIDAS (EU) for the vast majority of contracts and forms, though a small number of documents still require a handwritten signature — see our blog post on e-signature law for details.

Yes. ScanLens runs every scan, OCR pass, and PDF tool on-device using Apple's Vision framework. You can scan, OCR, sign, merge, split, and export PDFs with no network connection. Cloud sync to iCloud, Google Drive, Dropbox, or OneDrive is opt-in and only runs when you explicitly export a file.
Yes. ScanLens has a dedicated ID & passport mode with precise on-screen guides for driving licenses, national ID cards, and passport pages. Front and back are combined into a single multi-page PDF. All processing is on-device — your ID images never leave your iPhone unless you choose to export them.
ScanLens exports to PDF (single or multi-page), JPG, and PNG on every tier. Premium adds searchable PDF (PDF with an embedded OCR text layer), password-protected PDF (AES-256), and watermark-free exports. You can share via AirDrop, Mail, Messages, Files, WhatsApp, print, or any iOS share-sheet destination.
ScanLens OCR recognises text in 50+ languages, including English, Spanish, French, German, Italian, Dutch, Portuguese, Russian, Ukrainian, Polish, Czech, Turkish, Arabic, Hebrew, Chinese (Simplified and Traditional), Japanese, Korean, Vietnamese, Thai, Hindi, Greek, and more. Handwriting recognition is supported in major Latin and Cyrillic scripts. All OCR runs on-device using Apple's Vision framework.
No. ScanLens does not share document content with any third party. Scans and OCR text stay on your iPhone unless you explicitly export them. We use Apple App Store and RevenueCat for subscription billing — neither receives your document contents. We do not run ads, do not sell data, and do not include third-party analytics inside the scanning workflow.
Yes. ScanLens supports unlimited multi-page captures in Premium and up to 3 pages per batch on the free tier. You can scan continuously with auto-capture, then reorder, rotate, or remove pages before exporting a single PDF. The PDF merge tool also lets you stitch together separately scanned PDFs into one.
ScanLens is built around on-device processing — every scan, OCR pass, and PDF tool runs locally with no cloud upload required. CamScanner runs OCR in the cloud and has a history of privacy incidents (2019 malware payload through its SDK); Adobe Scan requires an Adobe account and sends scans to Adobe's servers for cloud OCR. ScanLens is iOS-native, has no account requirement on the free tier, offers a one-time Lifetime purchase that the other two do not, and never sends your scans off your device.
