With the advent of online file transfers, PDFs are among the most frequently shared and transferred files among educational, corporate, and legal institutions. As you can easily send, receive, read, and edit PDFs, a feature called Secured PDF provides the functionality to protect our privacy.
Secured PDF offers an extra layer of protection for your PDF files and allows you to control who can view, modify, and print them by setting a document password. It ensures the authenticity of your digital documents and prevents forgery and fraud.
What is a Secured PDF?
A secured PDF is a protected PDF. This means users cannot change or perform specific actions on the PDF file since it becomes a read-only file. In these cases, the secured PDF document may be encrypted or require an access code to open.
Organizations widely use a password protected PDF document to assure their clients that their documents are authentic despite being sent digitally. Documents signed with a digital ID or certificate are locked or protected to prevent changes. Organizations mainly use this for their legal and commercial contracts.
It is essential to secure copyrighted PDF documents as this ensures their integrity and authenticity when signing contracts. It also prevents forgery and unauthorized viewing and modifying of the marked and classified data.
PDF Security Levels
You can protect a PDF file using two ways: Encrypted and Password Protected PDF.
An encrypted PDF is one of the ways to protect a document from unauthorized users. Access codes and encryptions hide data within the file, allowing only authorized users to see the encoded data using the password security. You must have the cipher or algorithm and the key to decrypt the data.
Password Protected PDF
Password-Protected PDF is another way to protect a PDF document. This restricts a PDF to only certain users. Password protection can also restrict the editing and printing of the document. However, keep in mind that unauthorized users may still create digital copies of password protected files using this method.
There are two kinds of passwords for a PDF File to be password-protected pdf:
Document Open Password allows a user to open and view a PDF file.
Permission Password permits you to change details and settings in the PDF file. This method may also restrict printing, copying, and editing PDF files. You can also configure the document’s configure permission settings so that anyone may view your file but with limited functionalities. Unauthorized users cannot change the PDF settings if they set a password for your protected PDF file.
But if the secured PDF has a permission password and you don’t know it, you can use PDF Password Remover to remove the permission password so you can edit the protected PDF.
Can You Open a Secured PDF?
Yes. Generally, if you have the password from the author of the Secured PDF file, you can instantly open a secured pdf. For secured PDF files opened using Adobe Acrobat Reader DC, click File > Properties. From the Document Properties dialog box, click the Security tab.
If you have issues opening a password protected PDF file or are restricted from using certain features, you may contact the PDF author.
