PDF files are extremely versatile in terms of what you can use them for. They can be text documents, they can hold pictures, they support hyperlinks and more.

However, given the versatility of the format, you can end up using it as a support for more sensitive data. As such, you may want to limit the access that certain individuals have to that PDF file.

This includes the inability to edit it, print it, or even open it all together. On the other end of the spectrum, maybe you want to make a PDF file more accessible to everyone.

Whichever the case, we’ve created a step-by-step guide that will show you exactly how to change the security settings of your PDF files easily.

Note: This article takes into account the idea that you use Adobe Acrobat as your default PDF file reader.

By following these steps, you should be able to make a PDF file more or less restrictive while manipulating them with Adobe Acrobat.

This ensures that your PDF file cannot be edited, printed or even opened, even if unauthorized users get their hands on it. On the flip side, changing security settings can allow you to make a PDF document more flexible for a wider audience.
