@fabienmarry not really. JPEG does support progressive rendering, but you're restricted to a subset of the full image data. Here's a progressive JPEG https://random-stuff.jakearchibald.com/apps/partial-img-decode/?demo=fox.jpg&density=2 - it gets a first pass on screen in ~34kb. Whereas that AVIF example gets a 'frame' on screen in 800b, and a 'recognisable' version on screen in less than 9kb.
