How do I export a file?

The Export Tools: 

Original - No Annotation: This option will allow you to download the raw PDF file, perfect for if you are opening the document from the web and wish to save it locally.

With Annotations (PDF File): This will export your document with the annotations you have made. 

Annotations Only (Text File): This will create a text document with a summary of all annotations and comments made, including their location in the document and their type.

For those with premium, exporting can also be done to the cloud, allowing for the Original and both methods of exporting annotations on the PDF to your Google Drive directly. At this stage, Annotations Only is not supported to Google Drive.
