This is an extremely useful software to own. And if you use PDF-Exchange Viewer (freeware), instead of Adobe Reader, you will certainly know its usefulness especially when you have a document that does not allow you to highlight, mark, underline, make comment, etc, etc.

I bought a software, PDF Password Cracker before, (with such function as this), because after buying a PDF ebook, I noted that the publisher locked all rights, even of making personal comments, underlining, making personal notes. PDF-Exchange Viewer, which usually enables me to mark pdf file like personal notes, now cannot function as usual because of the lock. I emailed the author, but according to him, he does not know the password, because it is the publisher that locked it. So, I used PDF Password Cracker, and immediately removed the password, allowing me all the rights I used to enjoy using PDF-Exchange viewer.

Note that this type of software DOES NOT find the password, but removes the password, resetting it, as if no password was installed. And it only removes the password that restricts rights to the documents. That means that you can only use it on pdf file that you can open and read, but with rights restrictions. You cannot use this on pdf file that requires a password to open.

For pdf file that requires a password to open it, a pdf password finder, a giveawayof the day a few days ago, is the only solution, but it might take eons before you will be able to crack it if you do not have a hint of the password, making such software really useless most of the time. But this giveawayoftheday today is different, this is practically very useful for people who read pdf files like books.

Loaded a PDF that I had, which had a password protection. Typed in password, run the app and the passowrd is removed. It works well for PDF files where you know the password and have not forgotten the password. WHAT IT WILL NOT DO, is remove a password if you do not know it.
So what is this useful for? Well, if you have a PDF document that is password protected, and you know the password, it can remove it so that you NEED NOT TYPE IN the password everytime you wish to open the file.

To Ashraf:

Re.: Full review - PDFCrack – supplementary info

In your full review of PDF Password Remover you mention the free alternative PDFCrack to be command line (and open source), so I immediately asked myself "Linux? Unix? Surely not DOS? Windows compatible?.."
A (very quick) search gives the following.

Does it work in Windows?
Not yet. Feel free to make it work and send a patch. It can be built under Cygwin though and a kind user posted some unofficial binaries on the project forums that you might want to try.

OK, I'm impressed. I created a new PDF document with Adobe, placed a password on the document to restrict editing, tested that I couldn't make any edits and then ran the document thru this GOTD program (PDF Password Remover). The process was simple, it reported completion and, when tested, the newly saved file from this program was now editable.

Again, I'm impressed. A little scared my protected docs are now susceptible, but impressed nonetheless.

Thanks (I think) GoTD!
