A read-only PDF simply means that users can open and view the file and its contents but cannot manipulate or edit the PDF in any way. While the question of how to make PDF read-only is easy enough to answer, it does require special tools to apply such a permission restriction. This post will show you how to make a PDF file read-only so that others can't copy, edit or print the PDF file.
To create a read-only PDF for offline or online use, we recommend using Wondershare PDFelement - PDF Editor, a robust PDF editor with a wide range of functionality that includes password-based PDF encryption and the ability to set two types of passwords. One is for protecting PDF from being opened by unauthorized users and the second, which is relevant to this article, is to set a permission restriction make a PDF read-only PDF file. Let's look at the process of how to save a PDF as read-only so users can't edit it or make any other changes.
The following shows three simple steps to lock a PDF file for editing using PDFelement, while the final step shows you how to unlock the file so it can be edited by any PDF editor. Let's begin.
The first step is to import a PDF file into PDFelement. This is easily done with a drag-and-drop motion or using the "Open PDF" option in the main window. Once the file is open, click the "Protect" tab at the top of the window and then the "Set Password" button in the toolbar.
When you see the "Security" window, check the box for "Permission Password" and enter a password. The dropdown menus of the "Change Permission" will allow you to choose what type of restrictions you want to apply and what actions are allowed. If you don't want other people to copy the content of your read-only PDF file, you can deselect the "Enable copying text, images, and other content" checkbox. After setting the parameters, click on the "Save" button. The restrictions will be applied and only someone who has the permission's password will be able to unlock the restrictions.
Note: please don't set the "Open Password", as if you set the open password, others will have to enter the password to open the document, and it will be unreadable.
The final step is to save the file to a chosen location, which can be the local drive or a cloud storage account. Just click "File" > "Save As" to see the options.
Once the file is saved, you can check its properties to see what restrictions have been set by clicking the "File" > "Properties" > "Security" option.
After the above steps, the PDF file will be read-only. If others want to edit the file, they will need to click "Enable Editing" and then enter the set Permission password and click "OK" when attempting to edit the file.
If you don't want to apply such granular restrictions but merely want a version of your PDF file where the content can't be changed, all you need to do is convert it into an image file. You can do that in PDFelement as well. Here are the steps.
