Optimizers were created to reduce the image file size of your images so you can improve the speed of your web sites, blogs, and lead capture pages.
By optimizing your images, you will keep your visitors happy since if your sites are slow two things will happen 1) They will leave the site before the site loads and 2) you will get penalized by the search engines and you may not even show up in the top thousand searches.
It is always best practice to optimize your images BUT don’t over-optimize, or you may find the images may look blurry or pixelated.
Below you will find some links to optimizers to compress your images enjoy.
