How to disable editing of PDF files? Two methods are recommended!

In our daily work, we often encounter situations where we need to share important PDF files, but we also hope that the file content will not be changed at will. For this reason, setting modification restrictions on PDF files is a very effective measure. Today I will share two common methods for prohibiting modification of PDFs. Let’s take a look at how to set them up. Method 1: Use a PDF editor
PDF editors generally provide protection functions, and you can set a restricted password to prohibit editing of PDF.
First, open the PDF file through the PDF editor and click [Restrict Editing] under the [Protect] list on the menu tab.

How to set up password protection when you need to limit the editing permissions of PDF documents? Many times, we want to protect some PDF documents to prevent others from editing them at will. In this regard, PHP editor Apple introduced a simple method: use Adobe Acrobat Reader to set password protection. By setting a password in a PDF document, it can only be edited after entering the correct password. This effectively protects the security of document contents. Below, PHP editor Apple will introduce in detail the steps to set password protection for PDF documents to help everyone easily solve this problem.

After the settings are completed, click [OK] and save the file. At this point, the PDF file will be protected and cannot be modified by unauthorized persons.

If you need to modify the file later, or no longer need to protect the file, you can lift the "restricted editing".
First, open the PDF file through the PDF editor, and then click [Remove Security Settings] in the menu tab [Protection] list.

After the [Prompt] window pops up, enter the originally set password in the blank field, and then click [OK]. The "restricted editing" of the PDF will be lifted, and you can edit freely.

It should be noted that if you accidentally forget the password, you cannot remove the restriction through the PDF editor.
In this case, we can use the help of other tools.
