It's very easy for use as well as free so I don't have any complains about this tool in my side. Easy way of using software because all steps described properly on page which can be easily understood by user without having much knowledge regarding computer world or programming language also its compatible up-to windows 10/8 etc., The only problem i found here was when we try open pdfs from other application like chrome then our task manager shows some extra process running but if same happens while opening through adobe reader than no issue at all. Thanks God! Its helping me out to get rid off restrictions placed over documents via owner passwords so now am able tp do what ever needful thing related to document editing. Also sharing them among friends too since they're not getting access due to restriction setted by users who didn’t want others view their work even though there would never happen such case unless someone has malicious intention towards your valuable data. This program helps me remove restrictions from my pdfs! I have been able to save some of my favorite documents from being deleted in Adobe Acrobat Pro. The price is worth it if you can afford it. There aren't a lot of features, but what does it do? It removes owner passwords so I can use my own copies of PDFs instead of having them deleted when I close the original.
