Why You Need to Protect PDF from Printing, Copying, and Editing

The reasons for protecting a PDF document will vary from one person to another. But the following are the most common;

  • Copyright Protection

If your PDF document contains copyrighted information, the best way to prevent this information from being widely shared is to lock the document. The document may be protected under copyright infringement laws in your country, but not in other jurisdictions. Rather than spend time finding and stopping others from copying your work, you can simply lock the document.

  • Content Integrity

You may also lock the document to protect the integrity of the content. If you have added comments on various sections of the document, or you have already approved a particular version of the document, using a password to lock the document is one of the best ways to make sure you end up with the version you want.

  • Limiting Access

Of course, the greatest reason to password-protect a PDF document is to restrict access to the content of the document. If you don't want unauthorized persons to open the document, you can password protect PDF and you can use a permissions password to make sure that while they can see the content, they cannot edit it or reproduce it in any way.

FAQs on Locking PDFs with Restrictions

Can You Lock a PDF so it Cannot be Edited?

Yes. You can use a tool like UPDF to set up what is called a "Permissions" password. This password will allow anyone with the document to open and read the file. But based on the options that you select when creating the password, they will be unable to edit, copy, or even print any of the content.

How Do You Protect a PDF from Printing?

You can use a "Permissions" password to protect a PDF document from printing with UPDF. Once set up, anyone with the document will be able to open, read, and even make changes to the PDF document, but they will be unable to print it out.

How to Lock a PDF so it Cannot be Copied? How to Make a PDF Uncopiable?

You will need a PDF management tool that offers document protection features. But it is important to make sure that it has "Permission" protection features as well. Most tools will allow you to set up various permissions that can prevent anyone from opening the document, editing the content, printing the content, or even copying any of the content on the document. You can use these options to set up permissions to prevent the copying of the document as needed.


Protecting a PDF document is one of the most effective solutions if you want to keep confidential information on it from unauthorized access. But sometimes you may need to share the protected or confidential content with some individuals. If you only want them to read the document and not make any changes to the content, you can set up a permissions password that will lock PDF from editing, copying, and even printing the content. UPDF is an efficient, reliable, and simple solution to protect your PDF documents in this way. Try UPDF today and get an exclusive discount!
