Best Document Scanner Apps

Years ago, if you wanted to convert your paper documents into a digital format, you would need to have access to either a scanner or a sophisticated printer that could scan for you.

This is not the case anymore.

If you have a smartphone or tablet, you can simply download and use one of the many document scanning apps to convert paper documents into digital PDFs or images.

In this article, we'll take a look at some of the best mobile scanner applications you can download today!

What are scanner apps and what are they used for?

As the name suggests, scanner apps allow you to convert your paper documents into a digital format. This entails scanning everything from receipts to job invoices.

The best thing about these apps is that a lot of them are free to download. This means there is no more need to buy expensive optical character recognition (OCR) software and hardware.

Another benefit of using scanning apps is that they enable you to edit the file as necessary before saving. Thus, you can have a more accurate copy of your files.

Furthermore, several apps provide additional services for a small extra cost to assist you in organizing and optimizing your digital records. A few examples of the features these tools provide include advanced editing functionality, cloud storage, and automatic document sorting.

What makes a document scanner app great?

In order to evaluate a scanner app, you’ll need to create an account on the platform.  This may be accessible online or as a downloadable program. 

After that, you’ll want to perform tests on the program. Here are some things to look for in a good scanner app:

  • Auto-scanning: Even though every scanner app can scan your documents, choose those that will make it as easy as possible through auto-scanning. 

  • Accuracy: Check how well the OCR scans the document.

  • Organizing your files: Consider how well the app handles storing, sharing, publishing, and exporting scanned documents.

  • Customization: Document scanning and digitization might be the first step of a much longer process. Having the ability to personalize your documents is particularly crucial if you want to add extra text, a signature, watermarks, or additional security with a password.

  • Modes of scanning: As you might want to scan different types of documents, from IDs and passports to textbooks and invoices, different available scanning modes might be helpful for this purpose.

Moreover, you can preview the file in several sizes, as well as flipping, cropping, and adjusting the hue as needed.

Perhaps Adobe Scan's greatest strength is the seamless connection it provides to other Adobe applications. Because of this, not only can you scan documents into PDF format, but you can also make changes, add comments, digitally sign them, and share them with others.

To top it all off, Adobe Scan is free to download and use. However, you do have the option to make in-app purchases for more advanced functionality.
