Giveaway Of The Day recently offered a FREE licensed copy of PDFZilla. PDFZilla has a option to convert a PDF to Word, RTF or text file format.
I was a little surprised to discover that it can even convert PDFs with copy protection and as a result text can be copied from the converted file. I (naively?) believed that the a PDFs copy protection property was unbreakable. In fact there seem to be other tools as well that can bypass a PDF's copy protection.
I wanted to share this finding so that others wanting to protect their PDFs are not under the mistaken belief that the protection mechanism is reliable.
