Protect PDF from Unauthorized Access
Password protection can add an extra layer of security to a PDF by requiring a password before the document can be opened. This can be useful when a PDF contains private, confidential, or business-related information.
A strong, unique password is recommended for documents that contain sensitive information. Keep the password separate from the PDF when sharing the protected file.
Protect PDF from Editing, Copying, and Printing
Some PDF protection settings can also control actions such as editing, copying text, or printing. These permissions depend on the encryption and security features supported by the PDF format and the application used to open the document.
Password protection and PDF permissions are different from simply hiding or renaming a file. A protected PDF can use encryption and document security settings to control access to its contents.
Encrypt a PDF Online
PDF encryption protects the contents of a PDF using cryptographic security. When password-based encryption is applied, the password is used as part of the process for securing access to the document.
Encryption is particularly useful for PDFs containing financial information, business documents, personal records, contracts, reports, or other content that should not be openly accessible.

Protected PDF vs. Unprotected PDF
An unprotected PDF can generally be opened without entering a document password. A password-protected PDF can require authentication before its contents can be accessed, depending on the security settings applied during the protection process.
If you are sharing a PDF containing sensitive information, adding appropriate password protection can provide an additional security measure beyond simply sending the original file.
