In this blog, we gather collective insight into industry-best OCR software and draw a comparison. We're not trying to determine the best OCR solution in the industry but help you familiarize you with different features of most-popular automated data extraction solutions and help you find the most suitable one for you.

We start with a quick definition of OCR.

Let's jump right into it:-

What is OCR?

Optical character recognition (or, in short, OCR) is simply an awesome task that helps in automatically extracting text from images. A variety of modern OCR tools and services makes it pretty easy for users to comprehend complex tasks with relative ease.

By the end of the blog, you will get a complete overview of OCR and how the related software transforms the entire mechanism with absolute precision.

Why should an individual rely on OCR?

When we consider an OCR, we compare the technology with its performance. Normally, an OCR must identify the text of certain scanned documents, images, or photos. It also extracts scanned data from tricky documents and PDFs. This takes place by converting these data into machine-readable data for additional processing.

The technology is so appealing that many tech giants have shown a keen interest in leveraging its usage and productivity. Countless OCR text recognition technology paved the way for the user to perform ardent tasks with scanned PDF documents and different image types such as XML & CSV.

Not to forget that most companies determine different OCR based on their device compatibility, efficiency, performance, and data extraction capabilities. Here are some of the best software in the OCR business that you can't skip through:-
