Why can't PDF files be edited?

php editor Xinyi explains why PDF files cannot be edited. PDF file is a fixed format file, usually used to protect the content and format of the document from being modified at will. Therefore, PDF files generally cannot be edited directly. In order to edit PDF files, you can use specialized PDF editing tools or convert them into editable formats for modification.

First of all, please make sure that the PDF file you have is a scan, because the image format cannot be edited.

If the file is not a scan, you need to use a PDF editor to edit it. It cannot be edited when opened with a reader. If you still cannot edit it after opening it with an editor, it may be because the PDF file has been protected by restrictions, making it impossible to edit.

The PDF file has been restricted and protected. In addition to not being able to be edited, operations such as saving and printing can also occur. Related options are also gray and cannot be clicked.

So the restrictions must be lifted to edit PDF files.

If you know the originally set PDF restriction password, you can directly select [Protect] - [Secure Document] - [Remove Security Settings] on the toolbar

After entering the password in the dialog box and clicking [OK], the restriction on editing of the PDF file will be lifted.

If you don’t remember or don’t know the password, we can use other tools to remove restrictions, such as Pepsi Niu PDF Password Recovery Tool, you can directly remove restrictions and protection on PDF files without entering a password.
