Introduction

PDF files are widely used for storing and sharing information, but extracting data from them can be a challenging task. Optical Character Recognition (OCR) technology can be used to extract data from PDF files quickly and accurately.

Here’s a comparison table for three popular options to extract data from PDF files using OCR technology: Adobe Acrobat DC, ABBYY FineReader, and Readiris.

What is OCR technology?

OCR stands for Optical Character Recognition, which is a technology used to convert images of text into editable digital text. OCR technology works by using algorithms to analyze an image and recognize the patterns of the text characters within it. Once the text has been recognized, it can be converted into digital format that can be searched, edited, and manipulated just like any other text.

OCR technology has become increasingly important as more and more documents are stored in digital format. By using OCR technology, documents that were previously only available in paper form can be digitized and made searchable. This has made it easier for businesses and organizations to manage their documents and make them accessible to others.

OCR technology is used in a wide variety of applications, including:

1. Document management: OCR technology is used to scan paper documents and convert them into digital format, making them easier to manage and search.
2. Digital archiving: OCR technology is used to digitize historical documents, books, and other written works, making them accessible to a wider audience.
3. Data extraction: OCR technology is used to extract data from forms, invoices, and other documents, making it easier to process and analyze the information contained within them.
4. Accessibility: OCR technology is used to convert printed materials into digital format for individuals with visual impairments, making the information accessible to them.

OCR technology has come a long way since it was first developed in the 1950s. Today, OCR algorithms are much more advanced and accurate, and they can recognize a wide variety of fonts, sizes, and styles. However, OCR technology is not perfect and errors can still occur, particularly when dealing with low-quality images or handwritten text. As a result, it is important to carefully review the output of any OCR process to ensure that it is accurate and complete.
