Website owners use PDF files to distribute information to readers. PDF files have security permissions and password protection capabilities, so users are only able to read the files without changing the content. This is useful for read-only content such as user guides, e-books and contracts. To edit the file, the password can be removed or user permission restrictions removed. Removing the password automatically opens the PDF file from its restrictions, and it can be done in the PDF file settings.
