Using one of the default templates included with the app, or if you have created your own custom template, you can export your Confluence content to PDF.

To export, click ••• > Export to PDF 

This opens a dialogue box, where you can choose which template you want to use:

You can now define the scope of the export – whether you want to export only the current page, or the current page and its children:

Clicking Export will then confirm and generate the PDF.

You can change more export settings on the settings tab within the Template Editor.
