I've uploaded a 160k jpeg image today to an add-on, and it got recompressed to 285k on your cdn. Attached to this post is the original (I was curious whether it'd be recompressed as well). I suggest you store the original unless it's larger
Thanks for the heads up. I don't think I've touched our image management class for a good 6 years or more. Time to dive in there and see what the heck I was thinking back then.
