First off, the site uses Secure Sockets Layer (SSL) and https, so you're already using safe website. Secondly, IF YOU DON'T DELETE IT YOURSELF after you convert/compress your file they "keep" your doc for 2 hours and delete it forever. I personally don't wait and delete whatever I'm working with myself. In this day and age I'd never suggest you do something that compromises your personal info, and this isn't one of them. Heck, with all the govt hacking it's probably safer to do this than it is to upload all your personal docs to the CEAC site.
