MoverZ,

If you have gmail you should also have google docs. You can upload it there in PDF format (I do not recommend converting scanned PDFs to google docs) and then share it.

To share, open the file, then in the top left hand corner is a Share button. Select "Get Link to Share"

Then click the check box near "Allow anyone with the link to view (no sign-in required)"

Copy and paste link as desired.
