AVIF is a new image format for the web. Before I tell you all about it, let me show you what AVIF can do.
One way to compare image codecs is to encode the same image in different formats at matched file sizes and then compare the visual quality of the resulting images. For example, I rendered the AVIF below with a
q_50 quality transformation. It weighs 12.3 KB and, compared to the lossless original it looks pretty good subjectively.
