Remove password from PDF

Christmas time is also time to do some reading or studying. Often I upload the training material or books to my Kindle account and read on my tablet.

One annoyance are PDF files with password protection. So I went looking on how to easily and quickly remove password from a PDF file. Through the article "8 Free PDF Password Remover Tools" I ended up using PDFUnlock. Works very fast, both the up- and download part.
