Protect Your PDFs from Unauthorized Changes: How to Make PDFs Uneditable


PDF (Portable Document Format) is a widely used file format that is ideal for sharing documents electronically.

PDFs are known for their compatibility across different devices, their ability to maintain the original formatting of a document, and their security features.

However, there may be times when you want to make a PDF uneditable, so that no one can make changes to the original content.

This can be especially important if you are sharing sensitive information or legal documents.

In this article, we will discuss the various methods for making a PDF uneditable and how you can protect your PDFs from unauthorized changes.

How to make pdf uneditable?

Method 1: Disabling Editing

You can also make a PDF document uneditable by disabling editing.

This method will prevent others from making changes to the document, but will still allow them to view the document.

To disable editing in a PDF document, you can use Adobe Acrobat Pro DC or other PDF editors.

Here is how to disable editing in a PDF document in Adobe Acrobat Pro DC:

  1. Open the PDF document in Adobe Acrobat Pro DC.
  2. Go to “Tools” and select “Protect.”
  3. In the “Protect” dialog box, select “Restrict Editing.”
  4. Click “OK.”

Now, the PDF document is uneditable, and others will not be able to make any changes to the document.

However, they will still be able to view the document.

Method 2: Use PDF Password Protection

One of the simplest ways to make a PDF uneditable is to password protect the document.

This means that anyone who wants to make changes to the PDF will have to enter a password first.

Here’s how to password protect a PDF using Adobe Acrobat Pro:

  1. Open the PDF you want to protect in Adobe Acrobat Pro.
  2. Go to File > Properties, and click on the Security tab.
  3. Select the “Password Security” option, and then click on “Encrypt with password”.
  4. Enter a password and confirm it.
  5. In the “Permissions” section, select “Restrict Editing and Printing of the document”.
  6. Save the PDF and close Adobe Acrobat Pro.

Now, anyone who tries to edit or make changes to the PDF will have to enter the password you set before they can do so.

Method 3: Save as Read-Only PDF

Another option for making a PDF uneditable is to save it as a read-only file.

This means that the PDF cannot be modified, but it can still be viewed.

Here’s how to save a PDF as a read-only file in Adobe Acrobat Pro:

  • Open the PDF you want to protect in Adobe Acrobat Pro.
  • Go to File > Save As, and select “Read-Only PDF” from the drop-down menu.
  • Choose a location to save the PDF and click on “Save”.

The read-only PDF can be viewed, but not modified, making it uneditable.

Method 4: Use PDF Forms

If you want to make certain parts of a PDF uneditable, but still allow others to enter information, you can use PDF forms.

PDF forms allow you to create interactive forms that can be filled out by users. You can make certain fields uneditable, while others can be edited.

Here’s how to create a PDF form in Adobe Acrobat Pro:

  1. Open the PDF you want to use as a form in Adobe Acrobat Pro.
  2. Go to Tools > Forms > Create, and select “Forms”.
  3. Select the type of form you want to create (e.g. text fields, checkboxes, etc.) and place them on the PDF.
  4. Right-click on a field and select “Properties”.
  5. In the “Appearance” section, select “Read Only”.
  6. Repeat the process for all the fields you want to make uneditable.
  7. Save the PDF.

Now, users can fill out the form, but they cannot make changes to the uneditable fields.


In conclusion, making a PDF document uneditable is easy, and you have multiple options to choose from.

You can protect the document with password, or disable editing in the document etc…

Each method has its own benefits, and you can choose the one that works best for your needs.

Whether you want to share confidential information or simply preserve the formatting of a document, making a PDF uneditable is a useful tool to have in your arsenal.
