JPEG XL: new image format promises to consume up to 60% less space | Images

JPEG XL is a new type of image that promises to reduce the space occupied compared to other files. The proposal of the Joint Photographic Experts Group, the developer of the file, to be 60% smaller than the traditional JPEG. This way, with the same amount of storage, the cell phone, computer, pen drive etc. could store twice as many photos.

In addition, the idea is that JPEG XL offers more editing possibilities. Images in this format, in the future, may support transparency, HDR quality and even animations from multiple frames.

JPEG XL, according to the organization, will be able to improve the efficiency for saving images. Not only in physical storage, as in the internal space of smartphones or hard drives, but also in storage in the cloud and even improving Internet browsing.

With a file taking up less space, online storage costs tend to decrease. In addition, web pages with images in this format will be loaded faster, reducing consumption in the data plan.

Another advantage would be to offer a number of resources for editing. Allowing transparency, JPEG XL images could be superimposed without any major problems, eliminating PNG files. With HDR support, photos promise better quality, with the deepest black tones. In addition, files in this format could form animations, something similar to GIFs or Live Photos on iOS.

JPEG XL is still in the development phase and has no prediction of when it should arrive to the public. Its mass adoption is also subject to industry approval. Manufacturers like Qualcomm, Intel, AMD, ARM and Apple need to agree and add support for the new format. Unpacking can be a process that, if it does not have specific CPU support, can cause excessive energy consumption, compromising the autonomy of notebooks and smartphones.

Unpacking files using hardware is more efficient than using software. With that, the fear that file fragmentation may also be a problem in the future, something like what happens with video files many times, it is necessary to have specific software to open the content.

Apple has the HEIF (High Efficiency Image Format), which gained support on the company's systems last year. Google, Netflix and Mozilla are already supporting AVIF (AV1 Image Format). Which of these has the capacity to be the next standard image format only time will tell. Until then, JPEG has been reigning, as it did 25 years ago.
