Benefits of OCRing PDF files
You may sometimes find yourself with a lengthy text file in PDF format, but where you cannot access any of the actual text, because the file is stored as an image. This is a common problem for many people who work with scanned documents, including books, journal articles, and professional documents. Fortunately, by OCRing PDF files, you eliminate this problem.
Using OCR PDF Software
In order to resolve this problem and make an image file text-searchable, you need to use OCR software. OCR programs can be installed on your computer, and you can then select files that you want to OCR. The process is very fast, and can be even faster if you use a program with batch-processing capabilities.
Finding free OCR PDF software
You may find many websites offering free OCR software for PDF files, but many of these programs do not provide the level of quality that you would want in a professional tool, or even a one-time use for nonprofessional purposes. If you are looking for something more advanced, download the free trial version of Maestro Recognition Server from CVISION.
