This complete guide explains all available methods for digitizing your paper documents and converting them to PDF format, from smartphone cameras to physical scanners.

Why Scan to PDF?

PDF is the universal standard for scanned documents. It faithfully preserves the appearance of the original document and is accepted by all administrations, banks and companies.

The iOS Notes app includes a built-in PDF scanner. Create a new note, tap the camera icon, and select Scan Documents.

Method 3: With Google Drive on Android

Open Google Drive, tap the plus button, select Scan. The app uses the camera to digitize and automatically creates a PDF in your Drive.
