QUESTIONS

Protect PDF — questions

How strong is it?+
Standard PDF encryption (RC4 128-bit), which stops casual opening in every PDF reader. For secrets that need more, encrypt the file itself.
Can I remove a password?+
Not yet: a password-protected PDF can't be opened here. Remove the password in the app that set it first.
Is my file uploaded?+
No. Opening, editing and the password all happen in your browser.
