When I scan a multi-page document and email it, the attachment is a pdf, which I like. However, on numerous occasions, when I have scanned a single-page document and emailed it, the attachment shows up as a .jpg. I would like these to be pdfs but do not see an option to customize how my scanned documents get exported/emailed etc. Is there a way to ensure that single- and multi-page documents scan as pdfs? Thanks.
