What are Secured PDFs?

Let’s first understand what secured PDFs are. Secured PDFs are files that have been protected by their creators to prevent unauthorized modifications, printing, or copying. These security measures are often employed to safeguard sensitive information or intellectual property.

However, there may be instances where you have a legitimate need to make changes to a secured PDF, such as adding annotations, inserting or deleting pages, or modifying the text. With the right tools and techniques, it is possible to edit secured PDFs without compromising their security. Here’s how:

Method 1: Edit Secured PDF File using Adobe Acrobat Pro

Step 1: Download Adobe Acrobat Pro: If you don’t already have it installed on your computer, you can download a trial version from the official Adobe website.
Step 2: Open the secured PDF: Launch Adobe Acrobat Pro and open the secured PDF file by selecting “File” > “Open” from the menu. Locate the file on your computer and click “Open.”
Step 3: Provide the necessary password: If the secured PDF file is password-protected, you will be prompted to enter the password. Input the correct password and click “OK” to proceed.
Step 4: Navigate to the “Security” tab: Once the secured PDF file is open, click on the “Tools” tab in the top menu bar. From the tools panel on the right, select “Protect” > “Encrypt” > “Remove Security.”

Step 5: Save the edited PDF: After removing the security settings, you can now make the necessary edits to the PDF file. Once you have finished editing, click “File” > “Save” to save the changes to the PDF file.

Method 2: Using Online PDF Editors

If you don’t have access to Adobe Acrobat Pro or prefer a more convenient method, you can use online PDF editors that offer secure editing capabilities. Here’s how:

Step 1: Choose a reliable online PDF editor: There are several reputable online PDF editors available, such as Smallpdf, PDFescape, or Sejda. Choose the one that best suits your needs and ensure that it supports secured PDF editing.

Step 2: Upload the secured PDF: On the selected online PDF editor’s website, look for the option to upload or drag and drop your secured PDF file. Follow the instructions provided to upload the file.
Step 3: Remove the security restrictions: Once the secured PDF file is uploaded, navigate to the security settings or unlock features of the online editor. These options may vary depending on the editor you choose. Look for settings like “Remove Security” or “Unlock PDF” to proceed.

Step 4: Edit the PDF: With the security restrictions removed, you can now edit the PDF file using the available tools provided by the online editor. These tools typically include features for adding text, images, annotations, or even rearranging pages.

Step 5: Save and download the edited PDF: After making the desired changes, click on the “Save” or “Download” button to save the edited PDF file to your computer.
