Animated GIFs commonly need to stay as GIFs. But there are three different file types which you ought to take into account and recognize the way to use:
PNGs – extremely good for transparency and clean images/illustrations
JPEGs – first-rate for complex pictures and larger photographs
SVG – compressed vector pics for scalability
Not many designers realize that SVG may be smaller than PNGs relying on the export system. It all comes right down to this system you’re the use of and the type of photo you’re working with.
For instance, in Photoshop I’ll normally export JPEG files round a 65-70 at best, then run them through a picture compression tool simply to lower the filesize even greater.

Run Images Over a CDN
You oughtn’t constantly to optimize the image itself just for growth page velocity. Another alternative is to set up a CDN in your static files.

You want to take into account thumbnails for your page too in view that those can drain bandwidth if they’re oversized. Same holds proper for responsive websites that would get by using with barely smaller snapshots.
But there are no legitimate rules for photo sizes so play around and notice what fits excellent.
