What does it do?
Like JPEG, HEIF is a standard for lossy digital image compression. It’s a technology for maintaining some quality while keeping file sizes small; compared to a lossless technology like TIFF, which employs little to no compression but file sizes are very large. HEIF maintains the image quality of JPEG but at up to half the size, or offers better quality at the same size. It achieves this by comparing all the data of an image and only saving the areas that are different, instead of every piece of information (it’s more technical than that).
HEIF also supports animation, and is capable of storing more information than an animated GIF at a small fraction of the size.
it will be helpful if Edge supported this format so websites will be able to use this new format to display still and animated pictures more efficiently.
