Image compression basics:Does anyone have any tools or tips for optimizing website images for better loading speed?
I'm not using Wordpress, I'm using HTML5/CSS.
.png is lossless but a larger file size
.jpg is lossy but a smaller file size
now from within .jpgs you can set the compression. More compression = smaller file but worse quality. Less compression = bigger file but better quality.
If you can use the same image more than once, do that. Then the browser only has to load it once.
If they are return visits, it shouldn't matter because most browsers save images to the cache, so they only have to be loaded once.
