To unlock PDF file security you can use Softaken PDF Champ A few days back I was also searching for the tool that can unlock and remove PDF restrictions. However, after a lot of searches, I came across this utility. It really helps me to remove restrictions from PDF documents and enable all PDF permissions.

You have be a little more clear on the post.
PDF files have diferent protection levels. If you protect your pdf file with password, there is almost no easy or fast way to find the password.
The ways you have are:
1) Guessing the password (almost imposible).
2) Bruteforce (depend on password strenght)
3) Dictionary attacks (It depends on luck).
The second level is content protection to avoid printing, copy text, etc. This protection can be removed using some programs. I guess you can find free sw to do that, or you can write a python or perl script to do it.
Password protection can't be easily removed. |
