You might need to export your content to a different format. For example, you might need to use documentation you've written in Confluence in an e-mail, or on another website. You can do this by exporting part of a space, all of a space, or individual pages to HTML, Word, or PDF. There are plugins available that help you to export content into other formats
Go to the page you want to export.
Go to Tools | Export to PDF.
Your browser will prompt you to download and save the PDF file.
Comments on the page are not exported to the PDF file.
