Frequently Asked Questions
When to Use Protect PDF
Add password protection to your PDF before sharing sensitive documents. Protect PDF lets you set an open password (to restrict viewing) and a permissions password (to restrict printing, copying, and editing) — essential for contracts, financial reports, and confidential materials.
Tips for Best Results
- 1Use a strong password with a mix of letters, numbers, and symbols.
- 2An open password prevents anyone without it from viewing the PDF.
- 3A permissions password restricts actions like printing and copying even if the PDF can be opened.
- 4Share the password through a separate, secure channel — never in the same email as the PDF.
