Questions tagged [jpeg2000]

JPEG2000 is an image encoded format intended to supercede JPEG.

JPEG 2000 is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created in 1992) with a newly designed, wavelet-based method.

JPEG2000 is supported by Webkit based browsers (Safari, Chrome) on Mac OS X.

Why Google recommends using JPEG 2000 and JPEG XR and after Google Chrome doesn't support them?

Google recommends "Serve Images in Next-Gen Formats" and specifically mentions WebP, JPEG 2000 and JPEG XR, but then it doesn't provide support for 2 of them (JPEG 2000 and JPEG XR) in its own browser. Can someone please explain me why is this?
