Frequently Asked Questions
How do I password-protect a PDF?
Upload the file, enter a password, and the tool creates a protected PDF that requires that password to open.
What password should I use?
Use a password you can share safely with the intended recipient. Longer passphrases are usually easier to remember and stronger.
Can I set a separate owner password?
Yes. You can provide an optional owner password, or leave it blank to reuse the main password.
Will this change my PDF content or layout?
No. It adds password protection while keeping the document pages and layout intact.
Are protected PDFs stored after processing?
No. Files are processed temporarily to generate your output, then deleted automatically. Tiny File Tools does not require signup for these tools.
