常见问题
What types of protection can be removed?
We can remove user/owner passwords from PDF files. This allows editing, printing, and copying.
Is it legal to unlock a PDF?
Only unlock PDFs that you own or have explicit permission to modify.
What if I forgot the password?
The tool requires the correct password. We cannot bypass protection without the correct credentials.
