After finishing making a PDF, we should know one more thing and that is protecting or securing a PDF.
First, you should know Why Protect A PDF?
Adding password protection to your PDF can serve many purposes. On one hand, it makes sure that only people you gave the password to can open and consider the content of your file.
On the opposite hand, you’ll keep the people you send the PDF to from copying or printing your PDF document.
Files I Can Protect
Changes like adding a password can only be applied to Adobe PDF documents. However, it doesn’t matter what percentage of pages the PDF has or if it contains text, images, tables, and more.
You can also upload other file types like Word documents and pictures. we’ll convert them automatically to PDF and apply the passwords.
Password security basics
You can limit access to a PDF by setting passwords and by restricting certain features, like printing and editing. However, you can’t prevent saving copies of a PDF. The copies have equivalent restrictions because of the original PDF. Two sorts of passwords are available:
Document open password
A Document Open password (also referred to as a user password) requires a user to have A password to open the PDF.
A permissions password (also referred to as a master password) requires a password to vary permission settings. employing a permissions password, you’ll restrict printing, editing, and copying content within the PDF. Recipients don’t need a password to open the document in Reader or Acrobat.
They need a password to vary the restrictions you’ve set.
If the PDF is secured with both sorts of passwords, it is often opened with either password. However, only the permissions password allows the user to vary the restricted features. Due to the added security, setting both sorts of passwords is usually beneficial.

What is the difference between password protection and encryption?
When you protect documents with a password, people that enter the right password can access the file or folder. A stronger security method is encryption, with common types being 128-bit key or 256-bit AES encryption.
Encryption turns document content into unreadable ciphertext. To decrypt the document, authorized users need a key, which is usually a password or a digital certificate.
When you use the Acrobat online tool to feature password protection to a PDF file, it encrypts the file for added security. If you would like more advanced PDF security, you’ll try Adobe Acrobat Pro DC for free for seven days to feature encryption options, encrypt with certificates, or manage security settings to limit editing, printing, or copying.
