In keeping with each 9to5Mac and MacRumors, the iPhone 16 Professional fashions (and solely the Professional fashions, it appears) will assist capturing photos 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 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 would possibly assume. The Joint Photograph Consultants Group has moved to utilizing X on all their new codecs (JPEG XR, JPEG XT, JPEG XS) and the L stands for Legacy. JPEG-XL is meant to be the principle JPEG picture commonplace for the subsequent 20 years or extra, simply as JPEG has been so common for the final 30 years.
JPEG-XL is a quick, low-complexity (simple and quick to encode and decode by fashionable requirements), royalty-free and open-source format that was formally adopted by the JPEG group in 2020. 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 colour 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 probably beat codecs like HEIC at each compression and high quality.
Apple added assist for viewing JPEG-XL photos final 12 months in iOS 17, macOS Sonoma, and watchOS 10. It isn’t but broadly supported in picture enhancing instruments like Photoshop, however many corporations have expressed public assist for it.
