Protect PDF document with a password

PDFMall secures your data with TLS encryption and strong privacy practices. We never store your files; all processing data is automatically deleted within one hour. Rely on predictable privacy and security for your documents, every time.
Works Across All Devices
The Protect PDF tool works reliably across desktop, tablet, and mobile devices, making it easy to secure your documents wherever you are.
Protect PDFs from Editing and Copying with Passwords
Protect sensitive files—financial statements, legal documents, and confidential reports—by adding passwords to block copying, editing, or printing. PDFMall guides you to choose strong passwords and validates them for maximum safety.
How to set a strong password
Avoid weak passwords—enforce robust protection with at least 8 characters, including uppercase letters, numbers, and symbols (!@#$%^*). The stronger the password, the safer your document remains.
Enable Password Protection for a PDF in the Cloud
With PDFMall, password protection occurs entirely in the cloud. Upload your PDF, set a password, and download the encrypted file—no software installation required.
