Document Scanner: Scan to PDF

Turn paper documents, receipts, notes and forms into clean, sharp PDFs with your phone camera. Everything is processed on your phone.

SCAN
• Live edge detection finds the page while you aim
• Corrects perspective, so pages shot at an angle come out straight and at the right proportions
• Drag the corners to fine-tune, with a magnifier for precision
• Scan many pages in a row, or import photos from your gallery
• On phones with Google Play services, you can also use the Google scanner with automatic capture. On phones without it, the built-in scanner works fully offline. The app switches automatically

CLEAN UP
• Enhance: removes shadows and uneven lighting, makes the paper white and the text crisp
• Grayscale and black and white, great for printing and faxing
• Rotate pages and apply a filter to all pages at once

READ THE TEXT (phones with Google Play services)
• Recognize text: copy or share the text of a scanned document. Latin letters, Chinese, Japanese, Korean and Devanagari are supported
• Searchable PDF: turn it on in Settings and the PDFs you save or share carry hidden text, so other apps can search and copy it
• Recognition runs in Google Play services on your phone. The first time, Google Play services may download the language model itself; this app still has no internet permission

ORGANIZE AND SHARE
• Folders: group documents (receipts, contracts, IDs), scan straight into a folder, and move or delete several documents at once
• Multi-page documents: reorder, delete and add pages anytime
• Export as PDF in A4, Letter or the image size, and choose Original, Standard or Small quality with the estimated file size shown, so it fits an email or an upload limit
• Share the PDF or images straight to any app
• Save PDFs to Download and images to your gallery

PRIVATE BY DESIGN
• No account and no internet permission. Your documents never leave your phone
• Scans are kept only inside the app and excluded from cloud backup
• No ads

Improved automatic crop safety for imported screenshots. Unverified document edges now keep the full image instead of applying uncertain perspective correction. Manual corner adjustment remains available.
