How to keep iPhone in HDR when transferring to PC?

So today i was out celebrating my 5th year anniversary with my wife and i shoot this beautiful photo of her... I keep trying to send this HDR photo to myself through iMessage and E-mail in actual size...tried to send it from camera roll and iPhotos for iOS..but i noticed it doesn't look as good..not as bright and vibrant. I don't think it's the HDR version...can someone please help me out?

I'm using an iPhone 5s.
