A-PDF Password Security is a utility designed so that you can change the access password that you previously set for a PDF document.
The two main functions that A-PDF Password Security can perform are, on the one hand, to delete the existing password, and thus leave the PDF without a password so that you can access without problem; and, on the other hand, change that password to a different one.
To speed up the entire process, if there are many PDFs to modify, A-PDF Password Security allows you to delete / modify the passwords of the PDFs by processing them in batches. It also allows different levels of encryption to be applied to the PDF.
You can free download A-PDF Password Security 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
