How to Make PDF Read Only with 3 Easy Ways

Business documents sometimes contain confidential information that transfers to a hierarchy of individuals. It could be catastrophic for the organization if someone steals or alters your PDF document before reaching the final destination. Obviously, no one wants to let that happen.

Before finalizing your PDF document, make sure to set your document to read-only PDF. It will ensure that no one can copy, edit, print, or scan its content. In this article, we'll guide you on how to make PDF read-only in three easy ways.

What is a Read-Only PDF?

Before going further, you need to understand the read-only PDFs in detail. A read-only PDF is one of the PDF's encryption types by which a user can only open and view the document's contents but can't exploit the PDF whatsoever. In this way, your documents will remain much safe and more secure.

Read-only PDF encryption is only applied to password-protected PDFs. That means only the individuals with the permission password can manipulate the settings of a particular PDF. Putting your PDF on read-only is not a big deal if you have the right tool. Yes, placing encryptions and other permissions settings requires a separate tool to do your work.

As we mentioned, a document requires a tool to set PDF on read-only mode. Although tools like Adobe Acrobat or Foxit Reader would do the job, we'd prefer UPDF over them. There are many reasons for choosing UPDF - it's free and includes almost every feature.

UPDF is among the sophisticated tools present today. You'll find every possible advancement compared to Adobe Acrobat and Foxit Reader. UPDF offers many features that enhance how information is presented and increase productivity. Some of them are listed below:
