Questions
Is my password sent anywhere?
No. Encryption happens on your device, and Plainpage never sees your password.
Are my files uploaded?
No. Protect PDF runs entirely in your browser, so your files never leave your device. It even works offline once the page has loaded.
Is it free?
Yes, completely: no limits, no watermark, no sign-up and no ads.
