WebPlus X5: Tips on adding newsletter

I have produced a newsletter in Serif PagePlus X6 and now wish to place in on my web site using WebPlus X5. My first attempts using a pdf version look "lossy". I have tried saving the original file to a better quality pdf file but it still looks "lossy". The newsletter contains both text and photographs. Any ideas on the best way to put this newsletter on to my site?
Thanks
Chris
