đAbout This App
Document Scanner & PDF turns your phone's camera into a document scanner. Point it at a receipt, note, report, business card or any paper document and the app detects the edges automatically, lets you adjust the corners by hand, and converts the result to PDF. Scanned pages are organized into folders, can be reordered, cropped and filtered, and are saved as a local history you can revisit at any time. You can add a password to protect a PDF before sharing it, and send your files by email, messaging or any app on your device through the standard share sheet. Text recognition (OCR) reads more than 100 languages and turns a scan into editable, copyable text; it's a Pro feature, with a one-time free run available by watching a rewarded ad where offered. Backing up your scan history to a file is also part of Pro. Your documents and scan history stay on your device â nothing is uploaded to Yalintech servers, and there is no built-in sync to iCloud, Google Drive or Dropbox beyond sharing a file to those apps yourself. The app is available on iPhone and Android.

PDF Password Protection

Folders & Scan History
Organize scans into image and document folders, rename or move folders, and browse every past scan from the history page. Backing up that history to a file is a Pro feature.
â ī¸Limitations
- OCR text recognition is a Pro feature; free users get one free run per scanned item by watching a rewarded ad where offered.
- OCR runs on your device, but the recognition data for a language you haven't used yet downloads the first time, so the first run in a new language needs an internet connection.
- OCR works best on clear, well-lit, flat text; handwriting and heavily skewed or blurry scans recognize less reliably.

âFrequently Asked Questions
What can I scan with Document Scanner & PDF?
Receipts, notes, reports, business cards, photos and any other paper document you can capture with your phone's camera or import from your photo library.
How does edge detection work?
The app analyzes the camera image to find the document's edges and crops to them automatically. You can also drag the corners by hand if the automatic detection needs adjusting.
Is OCR text recognition free?
OCR is a Pro feature. Where offered, you can run it once for free by watching a rewarded ad; otherwise it requires the Pro upgrade. Pro purchases, including OCR, are not offered in every region.
What languages does OCR support?
The app's OCR engine supports more than 100 languages, including English, Spanish, French, German, Chinese, Japanese, Arabic and Hebrew.
Does OCR need an internet connection?
The app's text recognition runs on your device, but the recognition data for a language you haven't used yet downloads the first time, so you'll need a connection the first time you use a new language.
Can I create multi-page PDFs?
Yes. Scan or import multiple pages, reorder them, then convert the set into a single PDF.
Can I password-protect a PDF?
Yes. Set a password on a PDF before sharing it so it can't be opened without that password.
