JPEG may be fast enough for all of that, but is that also true for these newer ones? Decoding the .heic pictures from my old iPhone takes 1-2 seconds on my laptop(!!) As near as I could find out that's because the iPhones and macBooks and such all have hardware support for that, and my ThinkPad doesn't.
- eviks 3y agoAccording to the article I've linked above, JXL has twice as many points (don't remember actual speed comparison numbers) in the decoding speed comparison, and is also more parallelizable
- arp242 3y agoTo be honest I find that a little bit too vague to be useful. I can't find clear numbers on this, but on e.g. [1] I read it's not too fast, but I didn't try to reproduce their results, and according to some comments a number of factors can greatly affect performance.
