It's simple and can be done using their tool either online or using a downloadable desktop version.

Free OCR is the best software to translate my PDF docs to text for editing, I use it every time and it has never disappointed me, it's all about that convenience to be able to convert the docs flexibly.

This program is very user friendly and I can work on all my scans using it. I like how it interfaces directly with scanners in addition to importing image files and extracts text into a box from which you can cut and paste. The program is extremely easy to use and works well if all you want is text. It even extracts text from PDFs, though it exports only to text. I love how many of my clients will send me a scanned documents and all I need to do is convert it to the ocr to where I can copy and past the words into whatever program I am using.
