In keeping with each 9to5Mac and MacRumors, the iPhone 16 Professional fashions (and solely the Professional fashions, it appears) will help capturing photos within the new JPEG XL format. Whereas help from JPEG XL just isn’t listed on Apple’s specs, each websites declare to have seen code confirming it.
Customers will have the ability to choose JPEG XL Lossless or JPEG XL Lossy compression, and 9to5Mac even has Apple’s estimates for file sizes with every format:
- 11 MB for JPEG-XL Lossy ProRAW at 12 MP
- 18 MB for JPEG-XL Lossless ProRAW at 12 MP
- 20 MB for JPEG-XL Lossy ProRAW at 48 MP
- 46 MB for JPEG-XL Lossless ProRAW at 48 MP
By comparability, Apple’s ProRAW format (which makes use of the Adobe Digital Detrimental format .dng) is round 75MB for a 48 MP picture. So lossless JPEG-XL is round 40 p.c smaller.
What’s JPEG XL?
JPEG-XL doesn’t stand for “additional massive” as you may assume. The Joint Picture Specialists Group has moved to utilizing X on all their new codecs (JPEG XR, JPEG XT, JPEG XS) and the L stands for Legacy.

It takes the JPEG format into the fashionable period with help for enormous picture resolutions, HDR, lossy or lossless encoding, as much as 4099 channels (a number of shade channels, alpha/transparency, thermal, no matter), animation, a mode for artificial imagery like charts and graphs, and extra.
It ought to produce each smaller sizes and far greater high quality than present JPEG, and can probably beat codecs like HEIC at each compression and high quality.
Apple added help for viewing JPEG-XL photos final yr in iOS 17, macOS Sonoma, and watchOS 10. It’s not but extensively supported in picture enhancing instruments like Photoshop, however many corporations have expressed public help for it.
