WTF is JPEG XL?

And why should you care?

In partnership with

More than 30 years ago, a standards body called the Joint Photographic Experts Group launched an image format that took the world by storm.

The format was called JPEG, and it’s proven wildly successful, with billions of photographs taken every day using it.

But it’s getting long in the tooth. JPEG is a lossy format, which means it can drastically reduce file sizes — but at the expense of image quality.

The good news is the Joint Photographic Experts Group updated the format for the 21st century.

The new standard is called JPEG XL, and it’s reportedly coming to the iPhone. Here’s everything you need to know about JPEG XL.

One more thing ...

We've got really capable people at Apple. I made Tim [Cook] COO and gave him the Mac division and he's done brilliantly. I mean, some people say, 'Oh, God, if [Jobs] got run over by a bus, Apple would be in trouble.' And, you know, I think it wouldn't be a party, but there are really capable people at Apple. And the board would have some good choices about who to pick as CEO. My job is to make the whole executive team good enough to be successors, so that's what I try to do.
