Speed performance
SeoChecker displays in a table like this one below every image of the page that is not optimized, with its potential saving in KiB (kibibytes).
It is advisable to optimize every image in order to consume less data and to make page's loading faster.
The process of identifying optimizable images starts with a list of all the page's images (JPEG or BMP); once they are identified, SeoChecker brings them to a compression level of 85 and makes a comparison between original and compressed images: optimizable images are those that can result in potential savings of 4KiB or more.
