How to do PDF encryption? When we use PDF files, we often encounter file encryption, but when we make PDF files ourselves, when we want to encrypt them, everyone has no way to start. In fact, it is not difficult to encrypt files. We have many ways to do it. To complete our requirements for encrypted files, here are two methods that we can use every day to use files.
Package encryption
In fact, many people did not think of this method when they thought about encrypting PDF files, but I think it is a better encryption method, because it is not only PDF files that can be encrypted, but also other file formats that can be combined with PDF files. Put it in the bag and be encrypted together.
So how to encrypt? We put some files that we want to encrypt in a folder, and then use a compression tool such as "good compression", click the "add to compressed file" option, and then find the "set password" option in the parameter settings, just in the general The bottom button in the options.
PDF file encryption
In addition to this method, it is to encrypt your own PDF files. Of course, sometimes because the office needs to encrypt a separate PDF file, some people may send a compressed package, but if it is a separate PDF file, it seems that a compressed package is sent. It doesn't look good, so many people still hope to encrypt PDF files separately.
The following is the specific method. Using the Hi format PDF converter, we search for keywords on the computer and install this converter directly on our computer, then open the tool home page, select the [PDF encryption/decryption] option, and then enter the next layer Operation page.
After entering this level of operation page, we find that the [PDF encryption] function we need can be found in the options above, we click on this page, then upload the PDF file that we need to encrypt, then set the file password, and click [Start] Encrypt] option can encrypt our PDF files.
