What Is the Best Free PDF Scanner App?

In today’s world, having a reliable and easy-to-use PDF scanner app is essential for anyone who works with documents or other digital files. PDF scanner apps allow users to quickly and easily scan physical documents into digital formats, making it easier to store, share, and work with them. But with so many options on the market, it can be difficult to know which app is the best option for you.

The best free PDF scanner app should be easy to use, offer reliable scanning options, and provide enough features to make it worth your while.

It should also offer a variety of different scanning modes so that you can get the most out of your scanned documents. Many free PDF apps offer basic scanning capabilities such as black & white, grayscale and color modes, as well as more advanced features like OCR (Optical Character Recognition) and image enhancements. Most free PDF scanners will also provide some form of cloud storage in case you need to access your scanned documents from multiple devices.

Adobe Scan

Adobe Scan is a highly rated free PDF scanner app that offers exceptional OCR accuracy. It provides users with the ability to scan both physical documents and images into searchable PDFs using its Smart Scan feature.

Adobe Scan also includes features such as automatic document detection and edge detection for improved accuracy when scanning photos or textured surfaces. Additionally, Adobe Scan integrates seamlessly with Adobe Acrobat DC for easy editing of scanned documents.

Genius Scan

Genius Scan is another popular choice among users looking for a reliable free PDF scanner app. Unlike Adobe Scan which is focused on OCR accuracy, Genius Scan focuses on providing an intuitive user interface and an array of features that make it easy to scan documents quickly and accurately. Genius Scan includes several different scanning modes such as Color Balance Mode which helps improve images before they are saved as a PDF file.


When choosing the best free PDF scanner app for your needs, there are several factors to consider including ease of use, available features, accuracy of scans and integration with other services like cloud storage or editing tools like Adobe Acrobat DC. Both Adobe Scan and Genius Scan offer great options for those looking for a reliable free PDF scanner app but ultimately it will come down to personal preference for what works best for you.
