When you are dealing with important documents from professional and academic research sources, many of these documents are in a protected PDF format. Extracting text from these documents can seem nearly impossible. LotApps Free PDF to Text Converter is a free portable application that converts single or multiple PDF documents into Plain Text Format. You end up with a .txt file that may not be as pretty as the PDF, but at least you have the content. No PDF reader is required for this application to work. You can actually extract text from password protected and encrypted PDF documents.

Download the application:

After the conversion, a folder window will open containing the text file. Double-click on the file to view the text. It will look something like the screenshot below. All formatting will be gone and the text will span the entire screen.

In the next part of this article, we are going to take this a step further. This will explain batch file conversion to Docx, Doc, Rtf, Html, Txt, and PDF formats.

    “This is not intended for illegal purposes. Please respect copyright laws.”

    One could very well argue that the mere removal of the protection is already illegal. I’m sure courts in many countries would agree to that. So warning to respect copyright laws is a bit feeble as the whole article assists in illegal actions anyway.
