Method 1

To make a PDF read-only, you can add a permission password to it using AI PDF Reader. This way, you can control the editing, printing, and annotating permissions conveniently. Follow these simple steps:

Step 1. Launch the AI PDF Reader application and open the PDF you want to secure. Locate the "Protect Using Password" icon on the right-hand toolbar and click it.

Step 2. In the "Protect Using Password" menu, select the "Permissions" option. This allows you to restrict editing, copying, and printing by setting a permissions password.

Step 3. Enter your desired password in the provided fields. By default, setting this password will make the PDF read-only. To customize restrictions further, click "More Options" to adjust permissions for editing, printing, or copying.

Step 4. Click "Apply" and then "Save" to finalize your read-only PDF. Choose a file name and folder, and your protected document is ready!

Method 2

Another way to make your PDF read-only with AI PDF Reader is by converting it to an image-only PDF using the OCR tool. This method locks the content into a static, image-based format, unlike Method 1, which restricts permissions while keeping the text searchable and editable under a password. Here's how it works:

Step 1. If you haven't installed AI PDF Reader's OCR tool, do so first. Once installed, open the tool from the AI PDF Reader interface and click on the OCR option to launch a new window.

Step 2. In the OCR tool, choose "Image-only PDF" as the Document Type. This ensures your file is converted into a static format that cannot be edited or searched.

Step 3. Under the "Keep Pictures" section, select the image quality level—Low, Balanced, or High—based on your clarity and file size preferences.

Step 4. Click "Perform OCR," select a folder to save your new file, and let AI PDF Reader generate the image-only PDF.

This method permanently locks the PDF content by converting it to a static format, making it ideal for archiving or sharing documents without risking modifications or unauthorized text extraction.

Method 3

The third method to make a PDF read-only with AI PDF Reader is by utilizing its Link feature. Unlike the previous two methods, this approach doesn't modify the PDF file itself. Instead, it limits access through a secure link, giving you control over permissions such as downloading, copying, and printing. Here's how it works:

Step 1. Launch the AI PDF Reader app, click "Open File," and select the PDF you want to share securely.

Step 2. On the right-side panel, click on "Share this file with others." This will bring up menu options where you can configure sharing settings.

Step 3. Choose to disable copying, downloading, or printing for the PDF. You can also set an expiration time for the link to control how long it remains accessible.

Step 4. Click "Create" to generate a secure link or QR code. Copy the shareable link or send the QR code directly with users.

This method is ideal for temporary sharing where you need full control over access without altering the PDF file itself. Unlike Method 1, which uses passwords, or Method 2, which converts the file into a static format, this approach enables flexibility and revocability.

Part 2. Extended Reading: How Do I Remove Editing Permissions from a PDF?

In addition to making PDFs read-only, AI PDF Reader also allows you to remove the editing restrictions from PDFs. Here's how to disable editing with AI PDF Reader:

Step 1. Launch the AI PDF Reader application and open the PDF file you want to secure.

Step 2. Navigate to the "Protect" tab in AI PDF Reader's interface and choose "Remove Security".

Step 3. To disable editing restrictions, first enter the permission password.

Step 4. After that, click the "Unlock" button, AI PDF Reader will automatically remove the editing permissions for you.

Step 5. Click "Save" to finalize the changes. The document can be edited now.
