Summary
editDescriptionComparison of jpegxr2000.png |
English: This is a comparison between Jpeg XR, Jpeg 2000, and Jpeg. I tried to compress the photos as close as possible to 7KB but paint.net and infranview are not exact. The basic jpeg was the worst at compression but Jpeg XR and 2000 were very similar. The Jpeg 2000 is a bit on the brighter side and tended to do a better job at blending the pixels. The black areas in the Jpeg XR developed a checkerboard pattern when zoomed in. The original photo was cropped out of a very large jpeg and saved as a png. |
