Each article can be exporting to an individual PDF that will match the look and feel of your knowledge base. PDF exports can be toggled on and off globally as well as on an individual article basis.
While PDFs will have the same styles as your theme, you can override the styles for your PDFs using the CSS class "hg-pdf". This way, PDF articles can have styling different than your online versions.
For additional layers of security, watermarks and passwords can be added to your individual PDFs to prevent unauthorized sharing and access.
