Kelly Thompson: HEIF: A First Nail in JPEG’s Coffin?
"JPEG is 25 years old and showing its age. Compression has become a big deal as we’ve moved to 4K and HDR video, and HEVC was developed to compress those huge video streams. Luckily HEVC also has a still image profile. The format doesn’t just beat JPEG, JPEG 2000, JPEG XR, and WebP—it handily crushes them. It claims a 2 to 1 increase in compression over JPEG at similar quality levels. In our tests, we’ve seen even better levels, depending on the subject of the image."
HEIF looks cool, and Acorn will be supporting it on MacOS High Sierra when it ships in the fall.
