Why pick Convertify for this?
Files stay on device
Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.
No upload wait
Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.
No daily quota
Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many protect pdf jobs as you need.
No watermark
Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.

Frequently asked questions
How do I password protect a PDF?⌄
Upload your file, set a password, and download the encrypted PDF. Anyone opening it will need that password to view the contents.
How strong is the encryption?⌄
The tool applies strong PDF encryption so the document cannot be opened without the correct password.
What happens if I forget the password?⌄
There is no recovery — store the password somewhere safe. Without it, the protected file cannot be opened.
Can I protect sensitive documents like tax forms?⌄
Yes. Password protection is ideal for financial statements, contracts, and tax forms before emailing them.
Is the protection applied privately?⌄
Yes. Encryption runs in your browser, so the document and password never reach a server.
