How to Scan Documents Using Your Phone Camera

Overview

Turn receipts, contracts, and forms into crisp PDF documents using built-in scanner tools on Android and iPhone.

Quick takeaway: Start with standard verified settings, make one controlled adjustment at a time, and confirm the result before proceeding.

1. Using iPhone Apple Notes
Open the Notes app, create a new note, tap the Camera icon, and select 'Scan Documents'. Align the viewfinder over your paper.
2. Using Android Google Drive
Open the Google Drive app, tap the '+' floating action button, and tap 'Scan'. The camera automatically detects edges and enhances contrast.
3. Adjust corners and color filters
Adjust corner boundaries if needed, and choose 'Color', 'Grayscale', or 'Black & White' to eliminate shadows and optimize text legibility.
4. Save and share as PDF
Tap Save. Your multi-page scan is automatically compiled into a compact, standardized PDF document ready for email or upload.

Applying multiple configuration changes at once without noting what was changed.
Entering credentials or authorizing permissions without verifying the authentic destination.
Ignoring official software updates that patch active security vulnerabilities.
Relying on unverified third-party software for functions already provided natively.

Why is a document scan better than a normal camera photo?

Scanner tools auto-crop angles, correct perspective distortion, boost black-and-white contrast, and package pages into a single PDF.

Can you scan multi-page documents together?

Yes. Both iOS Notes and Google Drive allow scanning consecutive pages into one cohesive PDF file before saving.
