Remove security anytime.

When PDF password protection is no longer needed, it’s just as easy to remove it as it was to add it. If you own the document or have permission, protected PDF files can be unlocked with the correct password, and security options can then be adjusted as needed. Adobe keeps your original document perfectly intact.
