Have you ever needed a digital version of a paper document? For example, if you need to get a document to someone quickly, you might be able to email a digital copy instead of sending it through the mail or faxing it. Digital copies are also a great way to back up important documents in case the originals become lost or damaged.

You may already have experience creating digital copies with a desktop scanner, which is similar to a photocopier. However, many smartphones and tablets can actually capture high-quality scans of paper documents with their built-in cameras, which makes the process faster and more convenient than a traditional scanner.

Downloading a scanner app

Before you can scan a document with your smartphone, you'll need to download a separate mobile app to your device. These apps can convert text documents into PDF files, which is something most built-in camera apps can't do. There are many applications to choose from, but they all work in the same basic way. Some of the most popular scanner apps include Tiny Scanner (Android and iOS) and Scanner Pro (iOS), but you can also search your device's app store to find even more options.

To scan a document with your phone:
