> High Efficiency Image File Format being the standard designed to allow storing twice as much information as JPEG at the same file size while better image quality. Sounds neat. > HEIF is backed by the MPEG organization and, yes, involves patent licensing. Right. So as a Internet-format, it's pretty much dead in the water then.

  If it’s just a container-format, bragging about “high efficiency” sounds pretty rich. That this aspect of the file-format also makes the patent-status if the content uncertain or questionable (until inspected or attempted opened) is IMO something which makes this sound even less undesirable as a web-format.

> High Efficiency Image File Format being the standard designed to allow storing twice as much information as JPEG at the same file size while better image quality. I think that might be a controversial claim. For example, in this comparison:: http://nokiatech.github.io/heif/comparison.html http://nokiatech.github.io/heif/comparison.html HEIF and JPEG seem almost equal. HEIF wins on blurry parts of the image because it introduces fewer artifacts. But JPEG wins in noisy parts of the image because the artifacts look like the original signal. The last image shows this well - the white floor texture is blurred to nothing sooner in the HEIF image.

  In the last image, do the JPEG artifacts in the sky also look like the original signal? https://i.imgur.com/3jqTtVw.png https://i.imgur.com/3jqTtVw.png

    No, because that's a blurry part of the image where HEIF is better.
