User blog comment:Chris Mapping/Does anyone know why is Wikia blurring the maps?/@comment-25802715-20170307225759/@comment-25802715-20170307232111

The reason why jpg format does that is because jpg files compresses the pixels.

This blog lacks information regarding the issue. There are a lot of things to consider if you have this problem.

I just checked, chrome gave me the same issue while the browser I usually use does not.
