How to Remove Password from a PDF: Unlock PDF Files Free
Remove owner passwords and permissions from any PDF file online for free. Step-by-step guide to unlocking restricted PDFs you own without software installation.
PDF security features generally come in two forms: User (Open) Passwords that prevent unauthorized users from opening the file, and Owner (Permissions) Passwords that restrict printing, text copying, or editing. If you have forgotten an owner password for a document you created, or need to remove restrictions on a file you own, unlocking it is fast and simple.
Understanding User vs. Owner Passwords
Before attempting to unlock a PDF, it is helpful to distinguish between the two types of password protections:
- ✓ User (Open) Password: Prevents anyone without the password from opening and viewing the contents of the PDF.
- ✓ Owner (Permissions) Password: Allows viewing, but restricts secondary actions such as printing high-res copies, extracting text, adding annotations, or editing form fields.

Frequently Asked Questions
Can PDFTools unlock a PDF if I do not know the Open Password?
No. Strong AES-256 open encryption cannot be bypassed without the correct password. You must know the open password to remove it.
