Runs 100% in your browser
docflo processes this file using JavaScript on your own device. It's never uploaded, stored, or seen by anyone else — and it works even if your connection drops mid-way.
Frequently asked questions
What's the difference between the two passwords?
The password to open the file is required by anyone viewing it. The owner password (if you set a different one) bypasses the permission restrictions — useful for keeping edit rights for yourself while readers stay limited.
Can this be cracked?
docflo uses the PDF standard's own AES encryption. Like any password protection, strength depends on the password you choose.
Is Password Protect PDF free?
Yes, and there is no sign-up, watermark or daily limit — everything runs in your browser rather than on a metered server.
