You can't just use your iphone to photograph the document? I have all pics I take backed up automatically to Google Photos. Image quality is good enough on a phone to give you a great copy of the image.
They even have scanner apps that add a bit more functionality to the images. Cleaning up the edges, editable pdfs, and such.
Tiny Scan app. For example.

Isn't it called taking a photo with your smartphone and emailing the jpeg or the pdf?
