Protect PDF — Frequently asked questions
Is Protect PDF free for teachers?
Yes. Free for every classroom — no licence, no procurement request. There is no signup, no trial and no watermark on your files.

Protect PDF works with the documents teachers handle every day — lesson plans, worksheets, exam papers, student handouts, grading rubrics and permission slips. A common case: Merging a week of worksheets and answer keys into one printable packet for the class.
Where is my password stored?
It is never stored. Encryption happens in your session and the file is deleted afterward.
Can I remove the password later?
Yes. Anyone with the password can open and re-save the file without protection.
How do I put a password on a PDF?
Upload the file, type a strong password, and download an encrypted copy that will not open without it.
Can I protect a PDF before emailing it?
Yes. Ideal for contracts, financial and medical documents — share the password through a separate channel from the file.
What happens if I forget the password?
We never keep the password, so it cannot be recovered. Save it somewhere safe before sharing the file.
Does the password stop printing or copying?
The protection stops the file from opening without the password; once open, anyone with it can read and use it.
