A downloadable version of the doc is linked directly above the image. That does the job nicely, since it allows you to immediately edit.

newer browsers can actually just embed PDFs natively[0] in an iFrame, but there are more fault-tolerant ways to do it that provide a better ux.

Filestack also provides a great API for viewing PDFs in apps/browsers[2] that I use all the time.
