One of the elements that have the greatest influence on the speed of web pages are images.
However, nowadays, it is almost impossible to find a site that does not even have an image, since offering quality visual content to the user is very effective when we want to generate impact.
However, whenever we put an image we must think that this has the ability to negatively affect the speed of the website, so it is always recommended to do it intelligently. And the best option you have is to optimize them.
Shopify tells us that one second more in the loading speed of your site can mean 7% less conversion, but if it is the case that there was a second less this would lead to 27% more conversion. This is data that you definitely need to think about.
From the moment you understand that a user expects the web page they clicked on to load almost automatically when they open it, you will understand the importance of how images affect the loading speed of a website and you will do something about it.
When we don’t optimize images they are left in their heaviest form, which leads to more data being needed to open that website, which could take anywhere from 5 seconds to 20 seconds or more, depending on the size of the file we have added to it.
What you do when you optimize your images is to place them in the lightest form possible, making your website load much faster and generate a better experience for the user who may not have much time to wait for it to load in its entirety.
