The adoption of the 'JPEG XL' format in Apple's latest models, the iPhone 16 Pro / Pro Max, is drawing attention for its impact on photography. 'JPEG XL' offers improved image quality and significantly reduced file sizes compared to traditional JPEG, promising an enhanced smartphone photography experience.
This article explores what 'JPEG XL' is, how this new format contributes to photo quality, and Apple's vision for the future of photography.

What is JPEG XL?
'JPEG XL (.jxl)' is a next-generation image format that was officially standardized in 2022, boasting higher compression efficiency than traditional JPEG. This format offers high-quality images with file sizes up to 55% smaller than traditional JPEG, with minimal perceptible degradation.
Additionally, 'JPEG XL' supports HDR and wide color gamut images, allowing for richer expression of subtle color nuances and dynamic range. Notably, on the iPhone 16 Pro / Pro Max, ProRAW files compressed in 'JPEG XL' can be reduced to about one-fifth of their original size.
Why is JPEG XL Important?
The introduction of 'JPEG XL' not only enhances photo quality but also contributes to environmental sustainability. Smaller file sizes lead to reduced data transfer, which in turn decreases energy consumption. Apple's adoption of 'JPEG XL' aims to promote a more efficient and sustainable image format.
However, 'JPEG XL' is not yet widely adopted, and web browsers like Chrome and Firefox do not currently support this file format, meaning it is not immediately available across all platforms.
The Future of Photography Driven by Apple
For users of the iPhone 16 Pro / Pro Max, 'JPEG XL' opens up new possibilities in photography. It allows for storage savings while maintaining high quality, making it ideal for professional-grade photography.
With support for 'JPEG XL' already available in Apple's Safari and Finder, editing and sharing on iOS and macOS devices is seamless. However, full compatibility with external applications and platforms may take time to achieve. Nonetheless, Apple's bold adoption of this new image format could herald a future where high-quality photos are enjoyed across more devices.
