The amount of data that needs to be transferred to the visitor of a website has a significant impact on the time it takes to download. Images are one of the biggest factors contributing to the actual size of a page. Two important metrics by Google are influenced by images: Largest Contentful Paint and First Contentful Paint, with the first even being part of Core Web Vitals - a report examining URL performance.

Therefore, improperly coded images can increase load times and affect the responsiveness of any web store, which in turn can have a significant impact on conversion rates. By enabling webP and AVIF formats for image items, we can enhance the performance of plentyShop in regards to the metrics mentioned above.
