You can attach any file from the NG2 resources as an attachment to an email with the workflow component, Resource to attachment. The email can later e.g. be emailed or saved with this resource with either of the components, Create PDF email or Create EML with PDF. All email options are covered here.
Similar workflow components are:
Payload to attachment and URL to attachment. The component, Rename attachment is also related.
You can combine this workflow component with the Save in resources component.
The Resource to attachment components has these parameters:

Mime type
Here you can set a specific mime type for the attachment, so that the receiver can identify the file type. This is optional. Most often the extension of the attachment name should be enough to identify the mime type. Examples of mime types are listed here: https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types
