PDF files are commonly used for sharing and distributing documents, but sometimes you may need to add an extra layer of security to protect the sensitive information they contain. One way to achieve this is by password protecting your PDF files. While Adobe Acrobat is a popular software for this task, there are alternative methods available that allow you to password protect PDF files without using Adobe software. In this tutorial, we will guide you through the steps to password protect a PDF without Adobe.
Step 1: Use Google Chrome:
Open Google Chrome web browser and ensure you have the latest version installed on your computer. If not, you can download it from the official website.
Step 2: Open the PDF File:
Once you have Google Chrome installed, open the PDF file you want to password protect. You can do this by either dragging and dropping the file into a new Chrome tab or by right-clicking the file and selecting “Open with” and then choosing Google Chrome.
Step 3: Print the File:
Next, you need to print the PDF file using Google Chrome’s built-in PDF printing feature. To do this, press “Ctrl + P” on Windows or “Command + P” on Mac to open the print dialog box.
Step 4: Change Destination:
In the print dialog box, look for the “Destination” area and click on the “Change” button to open the “Print Destinations” menu.
Step 5: Save as PDF:
In the “Print Destinations” menu, select the “Save as PDF” option. This will change the destination to save the printed file as a new PDF.
Step 6: Set a Password:
Below the “Save as PDF” option, you will find a “More settings” link. Click on it to expand additional options. Here, you will see a checkbox labeled “Open PDF in Preview.” Enable this checkbox.
Step 7: Save the Password-Protected PDF:
Finally, click the “Save” button to save the password-protected PDF file to your desired location. You will be prompted to enter a password for the file. Choose a strong and secure password, then confirm it. Your PDF file is now password protected using Google Chrome’s PDF printing feature.
| Pros | Cons |
|---|---|
| 1. Requires no additional software or subscription, as it utilizes Google Chrome’s built-in features. | 1. Limited customization options for the password-protected PDF compared to dedicated PDF software. |
| 2. Works on multiple platforms (Windows, Mac, Linux) since Google Chrome is available for various operating systems. | 2. Password-protected PDFs can still be accessed by individuals who know the password. |

How secure is PDF with password?
PDFs with passwords can provide an additional layer of security to protect sensitive information. Here’s a professional perspective on the security of PDFs with passwords:
1. Encryption: Password-protected PDFs often use encryption algorithms to secure the contents. This means that even if someone intercepts the PDF file, they can’t access its contents without the correct password.
2. Strong Passwords: The security of a password-protected PDF largely depends on the strength of the password chosen. It is crucial to use a long and complex password that includes a combination of letters, numbers, and special characters. Avoid using easily guessable information such as personal details or common words.
3. Brute-Force Attacks: Brute-forcing involves systematically trying all possible combinations of passwords until the correct one is found. PDF password protection can be vulnerable to brute-force attacks if weak or common passwords are used. To enhance security, it’s recommended to use longer passwords and enable restrictions on the maximum number of attempts allowed before locking the file.
4. Offline Attacks: If an attacker gains access to the password-protected PDF file, they can attempt to crack the password offline using specialized decryption tools. It is important to select encryption algorithms with high security standards, such as AES (Advanced Encryption Standard), to minimize the risk of successful offline attacks.
5. Collaboration Risks: While password protection secures the content of the PDF, it might not safeguard the file in all scenarios. For instance, if the password is shared with unauthorized users or compromised due to poor security practices, the PDF’s confidential information may still be at risk. Always ensure that passwords are only shared with trusted recipients over secure channels.
6. Vulnerabilities and Updates: PDF software occasionally requires updates to address potential security vulnerabilities. Stay vigilant and regularly update your PDF reader or editing software to benefit from the latest security patches and enhancements.
7. Additional Security Measures: To enhance PDF security further, consider using additional security measures, such as digital signatures or watermarks. These can help ensure the integrity of the document and provide proof of its authenticity.
Remember, no security measure is entirely foolproof. While password-protected PDFs can provide a reasonable level of security, it’s essential to employ good password hygiene, implement strong encryption, and follow best practices to protect sensitive information effectively.

How do you password protect a PDF in browser?
To password protect a PDF in a browser, follow these steps:
1. Open the PDF: First, ensure that you have the PDF file you want to protect accessible on your computer or device. Most web browsers allow you to open and view PDF files directly within the browser window.
2. Convert to a password-protected PDF: Once you have the PDF open in your browser, you’ll need to convert it into a password-protected format. However, this functionality may vary depending on the browser you are using. Here, I’ll explain the process for two commonly used browsers:
– Chrome: Click on the three dots in the top-right corner to open the browser menu. From the dropdown menu, select “Print”. This will open a new print dialog box. Under the “Destination” section, click on the “Change” button and choose “Save as PDF”. Then click on the “More settings” option, scroll down to find the “Security” section, and check the box that says “Password protected”. Enter your desired password and click “Save”.
– Firefox: Click on the three horizontal lines in the top-right corner and select “Print” from the dropdown menu. In the print dialog box that appears, select “Microsoft Print to PDF” or any other PDF printer that you have installed. Then click on the “Options” or “Properties” button next to the printer selection. Look for a section related to security or password protection, enable it, enter your desired password, and click “Ok”. Finally, select a destination to save the protected PDF file and hit “Save”.
3. Test the password protection: Once you’ve saved the PDF with a password, close the print dialog box. Then try opening the newly saved PDF file to ensure that it prompts you for a password before allowing access. Enter the password and verify if it successfully unlocks the PDF.
By following these steps, you can password protect a PDF directly in your browser without the need for any additional software or third-party tools. Remember to keep the password written down or memorized to avoid losing access to the protected PDF.
