Frequently asked questions
Do I need to know the current PDF password?
Yes. Unlock PDF requires the current opening password for a PDF you are authorized to access.
Can Caspenda crack or recover a PDF password?
No. Caspenda does not provide password cracking, brute force, dictionary attacks, guessing or password recovery.
What happens if the PDF is not encrypted?
Caspenda tells you that no password protection was found and does not create a meaningless replacement file.
Is my PDF or password uploaded?
No. Unlock PDF processes the file and password locally in your browser for this workflow.
