Summary[edit]

Description
English: Comparison of jpg to jpg xr. The Original photo was a 7.3MB jpg. I converted this photo once to 300KB jpg and once to 300KB wpb (aka jpg xr). Both photos were converted using the program paint.net. I cropped all three photos on the same spot and connected the photos. The two converted photos were not exactly 300KB. The jpg was 302KB and the wdp was 305KB
