FAQ
What is the difference between user and owner password?
The user password protects opening the file. The owner password (optional) adds a permission lock that controls printing, copying and changes even after opening.
Which permissions can I control?
Printing, copying text, modifying content, annotating and form-filling — each individually allowed or blocked.
How strong is the encryption?
The PDF is encrypted with standard PDF security; choose a long, unique password for real-world security.
Can I remove the password again?
Yes — upload the locked file later and use the same protect tool to write a new password, or keep an unlocked copy of your original.
