While the JPEG format has dominated the world of digital images for years, its limitations, particularly in terms of image quality and compression, are increasingly felt. Google is working on this problem with a promising approach.
Since its creation, JPEG format is synonymous with digital photography and images on the internet. It is commonly used for its ability to significantly reduce file sizes. However, this compression comes with its share of compromises: loss of quality and the appearance of defects in photos which become more pronounced each time the image is re-recorded.
Facing the limitations of the JPEG format, Google set out to find a solution that could reconcile compression efficiency and quality integrity. The company, recognizing users’ needs to maintain high-quality images without sacrificing storage space, has developed technology that may well solve this equation.

Here is Jpegli, a format that promises to compress images without loss of quality
The solution proposed by Google is called Jpegli. This new format promises a significant improvement in the compression of JPEG images, reaching up to 35% size reduction compared to traditional methods, while minimizing loss of quality and defects due to compression.
Jpegli’s innovation lies in its approach to compression, which integrates advanced techniques from the development of JPEG XL, an even more recent and efficient format. Thanks to these methods, this new format manages to reduce noise while preserving more details in small files. This technical feat is all the more remarkable as it maintains a full compatibility with existing JPEG encoders and decoders, facilitating its adoption without having to modify current web infrastructures.

Beyond simple size reduction, Jpegli addresses long-standing issues associated with the JPEG format, such as quality degradation across multiple saves and inefficient handling of color tones and fine details. By allowing a smarter compression and respectful of the visual content, this format opens the way to better quality images on the Internet.
