When you upload a PDF, the tool checks for encryption markers. If the PDF is locked, it shows the unlock interface. If it's open, it shows the lock interface. No manual switching needed.
Your PDF is rendered at high quality and re-saved with AES-256 password encryption. Only someone with the password can open it.
PDFs with restriction-only locks (print/copy disabled) are unlocked instantly. Password-protected PDFs require you to know the password.
