Submitting large application: 6mb PDF??!

I was about to submit an application for an internship when I realized how huge the whole thing was. It’s a 14 page 6mb PDF. I was about to send it as an attachment, but stopped when I realized how inconvenient this might look to the editor. It will probably take up a whole lot of space in her inbox. So what are some alternative methods besides snail mail? Should I send a link where she can download it instead? Help.
