Magento images optimization is highly important. Especially, when a lot of information is adding into the website, and the site manager forgets to carefully check the size of the picture.
Also, when developers are working on a site, they can forget that a large number of pictures can be conveniently combined into sprites.
Frequent issues
- Images from the Magento theme are not combined into sprites
- Load large images that are not optimized
- Pictures have much more width and height than required inside the container, where they are wetted.
Why these problems must be solved with a Magento images optimization:
- Site load speed improves conversion
- The speed of the site increases the SEO ranking
