Frequently asked questions
How do I password-protect a PDF?
Upload your PDF to fixtdoc's Protect tool. Enter a password and choose which actions to restrict (printing, copying, editing). Click Protect to generate a locked PDF.
What permissions can I restrict?
You can restrict printing, copying text and images, editing content, and annotating. Each permission is toggled independently.
Is the encryption strong?
Yes. fixtdoc uses AES-128 or AES-256 encryption, the same standard used by banks and governments to protect sensitive documents.
Can I protect a PDF without uploading it to a server?
Yes. fixtdoc encrypts your PDF entirely in the browser. The file and your password never leave your device.
