How to scan a document with your phone

What you need

• The document on a flat surface with even light (window light beats the flash).
• A scanning app with edge detection. Android and iPhone both ship basic built-in options (Google Drive, Notes), and dedicated apps add better filters and export formats.

Step by step

1. Lay the paper down and kill the shadows. Nothing ruins a scan like your own shadow across the page; stand sideways to the light.
2. Open the app and point. A good app finds the page edges by itself and captures once the image is steady. Perfect framing isn't needed: perspective gets corrected.
3. Check the corners. If the automatic crop ate a margin, drag the corners manually.
4. Pick the filter for the paper. Document for printed pages; Black & white for photocopies or faint text; Whiteboard for boards; Photo when color matters (IDs, illustrations).
5. Add more pages for long documents and reorder them before exporting.
6. Export. PDF is the universal format for paperwork; Word or Excel if you need to edit the content; JPG/PNG to send it as an image.

Tricks that make a difference

• OCR (text recognition) lets you copy and search the text on the page — handy for reference numbers, appointments, or digitizing notes.
• Password-protect the PDF if it carries personal data and you're sending it over messaging apps.
• Compress before emailing long documents.
• Mind where your document goes. Many scanner apps upload your pages to their servers for processing. For contracts, IDs or medical records, prefer an app that processes everything on the device.
