About the PDF Password Protector

Add password protection to PDF files. The pdf password protector works directly inside your web browser, so you can protect your document files without installing any software or creating an account. Unlike most online tools that send your files to a remote server, Joy File Convert performs the password protection locally on your device using WebAssembly. That keeps your files completely private and removes the upload size limits that slow other services down. It supports PDF and more.
