In response to each and , the iPhone 16 Professional fashions (and solely the Professional fashions, it appears) will assist capturing pictures within the new JPEG XL format. Whereas assist from JPEG XL is just not listed on Apple’s specs, each websites declare to have seen code confirming it.
Customers will be capable of 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 giant” as you would possibly suppose. The Joint Picture Consultants 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 trendy period with assist for enormous picture resolutions, HDR, lossy or lossless encoding, as much as 4099 channels (a number of coloration 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 increased high quality than present JPEG, and can doubtless beat codecs like HEIC at each compression and high quality.
Apple added assist for viewing JPEG-XL pictures final yr in iOS 17, macOS Sonoma, and watchOS 10. It isn’t but broadly supported in picture modifying instruments like Photoshop, however many corporations have expressed public assist for it.
