Password Protect Existing PDF Online with Ease

In today's digital age, protecting sensitive information and intellectual property has become a crucial aspect of online security. One effective way to do this is by password-protecting your existing PDF files. In this article, we will explore how to password protect an existing PDF file using two popular tools: CleverPDF and SmallPDF.

Protecting Your PDF File with CleverPDF

To begin, you need to upload the selected PDF file onto the CleverPDF tool interface. Select the PDF file from your computer and click on the Open button. Alternatively, you can browse to this link and click on the Choose file button to upload the PDF file you want to protect.

CleverPDF offers more features than SmallPDF, allowing you to restrict editing, copying, and printing of the documents apart from protecting them with a password. The tool stores two passwords in the same PDF file - one used to open and view the file, while the other removes the restriction of editing, copying, and printing.

To password protect your PDF file using CleverPDF, follow these steps:

1. Upload your selected PDF file onto the CleverPDF tool interface.

2. Fill the two password boxes with the same password on both boxes.

3. Click on the ENCRYPT PDF button to protect your PDF file.

4. Once the encryption process is complete, click on the DOWNLOAD button to save the protected PDF file on your PC.

Protecting Your PDF File with SmallPDF

To password protect an existing PDF file using SmallPDF, follow these steps:

1. Upload your selected PDF file onto the SmallPDF tool interface.

2. Fill in the password text box and repeat it for confirmation.

3. Click on the Encrypt PDF button to protect your PDF file.

4. Once the encryption process is complete, download the protected PDF file.

Password protecting your existing PDF files with CleverPDF or SmallPDF is a straightforward process that can be completed online. By following these steps, you can restrict access to sensitive information and intellectual property, ensuring it remains secure and confidential. Remember to use strong passwords to prevent unauthorized access to your protected PDF files.
