How do I encrypt my important Adobe PDF files?

The protection of the privacy of the file is very important, especially the Adobe PDF files we often use, how to encrypt Adobe PDF files. There is no efficient way to share it, just learn how to use the SanPDF online converter.

Before encrypting the Adobe PDF, let’s take a look at what Adobe PDF encryption is and the concept of Adobe PDF.

Adobe PDF: The Portable File Format is a unique cross-platform file format developed by Adobe. Adobe PDF files are images based on the PostScript language model. No matter which printer ensures accurate color and accurate printing, it will faithfully reproduce the original Adobe PDF of each character, color and image.

Benefits of Adobe PDF: The advantage of Adobe PDF format is that once the editing is completed, no matter what operating system, display of any size and resolution, no matter how it is printed, the layout format will not be messy, so the document is often converted into Adobe PDF format.

Adobe PDF encryption: Encrypted Adobe PDF files can be restricted according to the situation, such as: not allowing people to print, not allowing people to change comments and so on, not to let people look at it. Although the current Adobe PDF file can be encrypted with 40 and 128 digits, the security measures are not good, and it is easy to be cracked by the cracking software.
