Tech for Dummies: How to Scan a Document With Your Phone—No Scanner Needed

You need to email a signed form, save a receipt, or send someone a copy of a document.

You don't need a scanner.

Your iPhone or Android phone can turn a paper document into a clean digital copy in a couple of minutes. The important part is using the phone's document-scanning feature, rather than simply taking an ordinary photograph.

Here's how.

On an iPhone: Scan a Document With the Notes App

Apple builds a document scanner into the iPhone.

Open the Notes app and either create a new note or open an existing one.

Tap the attachment button and choose Scan Documents.

Position the document inside the camera view.

The iPhone can detect the edges of the page and capture it automatically. If it doesn't, use the shutter button to capture the page yourself.

Check the corners shown on screen. Adjust them if the iPhone didn't identify the edges correctly, then keep the scan.

If your document has several pages, keep scanning. You don't have to create a separate file for every page.

When you're finished, tap Save.

You now have a document scan rather than a pile of individual camera pictures.

Want to Email or Text It?

Open the scanned document and tap the Share button.

From there, you can choose an available app such as Mail or Messages, save the document to Files, or use another sharing option installed on your phone.

Before sending anything sensitive, double-check the recipient.

That's especially important with tax documents, identification, financial paperwork, medical paperwork, or anything containing account numbers or other personal information.

Android: Use Google Drive's Document Scanner

Android phones vary more than iPhones, but Google's Drive app includes document-scanning capabilities on supported devices.

Open Google Drive.

Look for the camera/scan option used to scan a document.

Point the camera at the paper and capture it.

Review the scan before saving it. Depending on the current version of the app, Drive can provide tools for adjusting the crop, cleaning up the image, rotating it, or adding additional pages.

When you're satisfied, save the scan.

Google Drive can save the resulting document to your Drive account, making it available from your phone and other devices signed into that account.

The exact buttons can differ somewhat by Android version, phone manufacturer, and Google Drive version.

Why Not Just Take a Picture?

You can.

If you're texting someone a picture of a restaurant receipt, an ordinary camera photo may be perfectly adequate.

Document scanning becomes more useful when you're dealing with forms, contracts, receipts, letters, or several pages.

A scanner can identify the edges of the paper, straighten the page, crop out the kitchen table underneath it, and make the result look more like a document.

That makes the file considerably easier for someone else to read.

Put the Paper Somewhere Flat

Your phone's software can fix a lot, but give it a decent starting point.

Put the document on a flat surface with good lighting.

Try not to cast a shadow over the paper with your phone or your hand.

If the paper is white, putting it on a darker surface can also make the edges easier for the camera to distinguish.

Before saving, zoom in and make sure the small print is actually readable.

This matters much more than making the scan look pretty.

Scan Several Pages Into One Document

This is one of the biggest advantages over simply photographing paperwork.

If someone sends you a five-page form, scan the pages in order as part of the same scanning session.

Then check them before sending: Page 1, Page 2, Page 3, Page 4, Page 5.

It's surprisingly easy to miss the back of a page or accidentally scan two pages in the wrong order.

Checking now is easier than getting an email tomorrow saying, “Page three is missing.”

Don't Forget the Original

Scanning a document doesn't automatically mean you should throw away the paper.

Keep original legal documents, signed contracts, tax records, titles, certificates, receipts needed for warranties, and other paperwork when the original may still be required.

The phone scan is a digital copy. Whether that copy can replace the original depends on what the document is and who requires it.

Tech for Dummies Bottom Line

iPhone: Open Notes → create/open a note → attachment → Scan Documents.

Android: Open Google Drive → use its document scanning/camera option → scan → review → save.

That's it.

The next time somebody says, “Can you scan that and send it to me?”, you don't need to own a scanner—or drive somewhere looking for one.

Your phone can probably do the job that's already in your hand.
