How to keep file sizes small & keep quality

Does anyone have any suggestions re this problem? My file sizes in swf are still too large and slow to view on my website stories in I am using vector lines and economy of content for each “page” of my kids books but still they are too slow. Julie


You know, .swf is deprecated. Tablets don’t support it, android neither.
Since the future is mobile devices you should change that soon. Youtube is doing it.
Even Adobe said that flash has … passed away.

What I recommend is convert them to video and link them from vimeo or youtube.
