How does OCR work?
The purpose of OCR is to convert images containing scanned text into actual text. OCR stands for optical character recognition. As this name suggests, the purpose of OCR is to recognize text characters in a scanned file based on their optical properties. In other words, the software traces the outline of every letter, number, and symbol in order to identify it by comparing it to information in its memory. This process happens very quickly, so that hundreds of pages can be OCRed within seconds. In this way, OCR software makes entire documents text-searchable.
What types of OCR exist?
There are different types of OCR software for different uses. Basic OCR software can be used to make any document text-searchable, simply by identifying the text characters that appear on the page. However, there are also other, more complex OCR tools. Some are designed to help process specific document types. For example, programs for forms processing can recognize different data fields on a page, and OCR documents by section in order to help the user organize information.
Using free OCR for bulk scanning
If you need OCR for bulk scanning, there are tools designed specifically for that. Batch OCR makes it easy to process files in bulk because it OCRs entire groups of files at once. It may be difficult to find free OCR tools with batch processing capabilities, but you may wish to try a few free tools in order to understand how OCR works. You can also explore the wide range of OCR solutions for bulk scanning that you will find on the market in order to find the one that is best tailored to your needs.
