How to Scan Documents Using Just Your Phone

You don’t need a bulky flatbed scanner cluttering your desk anymore. Whether it’s a receipt for your accountant, a signed contract you need to email, or your grandmother’s handwritten recipe, your phone can capture clean, professional-looking scans in seconds. Here’s how to digitize paper without downloading anything extra.

iPhone: Using the Notes App

Apple built document scanning directly into the Notes app, and it works better than most dedicated scanning apps.

Open a new note or an existing one. Tap the camera icon above the keyboard, then select “Scan Documents.” Your camera view will appear. Position the document on a flat surface with decent lighting—natural light from a window works best, but avoid harsh shadows.

Your iPhone will automatically detect the document edges and capture the scan when it senses the phone is steady. If it struggles to find the edges, you can press the shutter button manually and drag the corners to match the page. Keep scanning multiple pages; they will stack into a single document. When finished, tap “Save,” and your scan appears as a PDF attachment in your note.

To share it, tap the scanned image, then the share button. You can send it as a PDF via email, message, or save it directly to your Files app.

Android: Using the Drive App

Google Drive includes a scanning function that works on most Android phones. Open the Drive app, tap the colorful plus icon in the bottom-right corner, and select “Scan.”

Your camera will activate. Hold the phone steady above the document. Drive automatically detects edges and captures the image, but you can tap the shutter button if the auto-capture seems sluggish. After capturing, you can adjust the borders, rotate the image, or change the color mode between “Black and White,” “Color,” or “Color Drawing.”

Tap the checkmark to save. The scan uploads as a PDF to your Drive root folder by default, though you can move it to specific folders afterward. Like iPhone’s method, you can scan multiple pages in succession before saving.

Getting Professional Results

Lighting makes the biggest difference. Shoot near a window but avoid direct sunlight that creates glare. If shadows fall across the page, hold your phone higher and zoom slightly rather than casting your own shadow over the document.

Contrast helps edge detection. Place white paper on a dark table, or use a dark background if scanning a white receipt. The software needs clear boundaries to crop correctly.

For wrinkled receipts or folded contracts, flatten them under a heavy book for a few minutes first, or gently hold down the corners with your free hand while scanning.

What About Third-Party Apps?

While built-in tools handle most tasks, you might need specialized features. Some dedicated scanning apps offer optical character recognition (OCR) that converts scanned text into editable Word documents. Others provide automatic cloud syncing to specific services like Dropbox or OneNote.

However, for simple archiving and sharing, your phone’s native tools produce sharp, legible PDFs without the subscription fees or privacy concerns that come with third-party software.

Organizing Your Scans

Without a physical filing cabinet, digital documents can disappear into your camera roll. Create a specific folder in your Files app or Google Drive called “Scans” or “Documents.” When you save or share, send everything there immediately. Rename files from the default “Scan_2024” format to something descriptive like “Rent_Receipt_Jan” while the context is fresh in your memory.

Once you get the hang of positioning the camera and trusting the auto-crop feature, you’ll find yourself reaching for your phone instead of the printer’s scanner glass every time.
