Best Tool to Unlock Password Protected PDF Files
edwinjhofferFebruary 25, 2015
Pros
User Interface Features Price Remove User as well as Owner level restrictions
Cons
You should know the password before removing owner level (when PDF file asked you to fill the password while opening) restrictions.
Summary
I always prefer downloading software from CNet (i.e. download.com), because here all software are virus free. Some days ago I got a file from my office colleague, the file was restricted for editing, and I have to do some changes in it. While searching on Cnet I found this tool, I tried it and saw that it doesn't ask me about the password which were used to locked restriction of the PDF file. But now the problem is it give watermark on the PDF Files, so I bought the software and did some changes those were needed for me. Thanks
