Sharing a sensitive document — a business proposal, a personal ID, or financial records — as an unprotected PDF is a risk. Anyone who receives it can forward it freely. Convertly.ng's free Protect PDF tool lets you add a password to any PDF in seconds, so only the right people can open it.
Why Password-Protect a PDF?
- Protect confidential business proposals from being forwarded without permission
- Secure personal documents like NIN copies, passport scans, and bank statements
- Control access to academic research, reports, and proprietary content
- Add a layer of security to contracts before sending by email

🔐 Password Security Tips
Use a strong password of at least 8 characters mixing letters, numbers, and symbols. Share the password via a different channel — never in the same email or message as the PDF itself. Store it somewhere you won't forget; a lost password means a locked PDF.
