Very cool.
Which reminds me, what the heck happened to old-school progressive JPEGs? I remember seeing them a lot in the early days of images on the internet, but it seems like you don't see them around anymore. Why is that?
- theandrewbailey 4y agoThey're still being used. A newer, optimized JPEG encoder, mozJPEG[0], seems to use progressive encoding by default. I suspect with faster internet speeds, most JPEGs download and decode so fast that the cool 'enhance' animation is rarely seen anymore.

- bick_nyers 4y agoFor it to be worth the effort to implement/maintain your users need to be bandwidth-constrained, which is not really a reality anymore, jpegs don't take upwards of a minute to load for most people. It has applications still, such as in medical imaging.
- jonsneyers 4y agoIf you treat progressive jpeg and sequential jpeg as separate image formats, then progressive jpeg is currently the fastest growing image format on the web. If you look at the statistics, the opposite is true of what your feeling is. One thing that did change is that often the network is fast enough to make it unnecessary to show progressive passes, or if they're still shown, it happens quickly enough to be not really noticeable.
