PDF files (Portable Document Format) have become a standard for digital documents not only for the dissemination of documents on the internet but also for business and business use. The reason for this success lies in the fact that the pdf document has the advantage of being a perfect and mirror copy of a document written with any program. The file created is exactly what you prepared, regardless of the software used to create or read a file with the chosen format and characters, completely independent of the configuration of other people's computers and the programs it uses. The PDF Reader is used by everyone and works for everyone in the same way.
In addition to this there are many other options that make the pdf document of great value and a powerful tool in everyone's hands.
However, sometimes you receive a PDF file from a friend or colleague or download it from the Internet and you find that it is protected by a password and you cannot read it because it is completely blocked. Some pdf files require a password to open and read them, others instead to print or modify them.
In particular, we try to understand how a protected pdf file can be opened to be read and printed .
READ FIRST: Unprotect PDF remove protection, recover and disable password
1) The software to use is free and is called Freeware PDF Unlocker . Freeware PDF Unlocker is a free program that allows you to delete passwords and open protected PDF files. Its logic lies in creating a copy of the protected pdf file, obviously a copy unprotected and free to be opened, read and printed without limitations.
The only drawback is that this program does not have a graphical interface, a GUI, which guides the user to unlock the file and must explain how it works.
When you install this software, a CMD file is created on the desktop called PDF Unlocker ; all you need to do to unlock the protected file is just to drag the pdf file icon to the PDF Unlocker icon. Same thing to remove the password that protects the pdf from copying and printing, what this program does is simply to create a passwordless copy of the pdf itself.
It should be clarified that this program was not actually developed for cracking pdf file passwords but would only help to avoid remembering too many passwords. If a friend sent us a protected file, I would assume that you also send the password but, after a month, this password can be lost or forgotten, so it can be useful to use Free PDF Unlocker. Basically, you make a copy of the desktop shortcut, put it next to the pdf file whose password you know, rename the " PDF Unlocker " file in the following way: "password document foo", open the file ( right button on the file -> edit ) and on the line where -sPDFPassword = is written, insert the known password after the same. Now this program is not a hoax but it doesn't always work.
2) Another program to unlock a protected PDF to try is BeCyPDFMetaEdit which allows you to unlock the PDF by removing the protection option (encrypt) by simply checking a box. After unlocking, the file can be opened normally without a password request.
Another possibility to remove the passwords of a protected pdf file is given by the PDF Unlock site (ex PDFPirate) to which the file must be sent and then received without protection and unlocked.
3) Free My PDF instead allows you to unlock a PDF document if it is not possible to edit, copy or print it. It only works if the file can be opened and read.
4) PDF Password Remover Tool is another tool to unlock password protected PDF for editing and printing.
5) Among the online tools, we point out the PDF-Crack site which allows, not to delete passwords but to unlock those files that have been protected from copying, modification and printing. To use it, you just need to send the protected pdf file and receive the download of the unlocked version.
6) IlovePDF is a free site that allows you to unlock a protected PDF by removing the password to open it, easy, fast and free.
7) PDFCandy is another site to try, with the online tool to unlock the PDF

Cut and join, separate and unify pdf files with PDFMerge
Create free online pdf files directly from the internet
