Google’s New JPEG Encoder Offers Better Quality and Significantly Reduces Image Size

Google’s new JPEG encoder offers better quality and significantly reduces image size.

Video makes up more than 80 percent of all online traffic, but photos also play an important role in the digital experience. The bandwidth consumed by data costs money, and tech giants like Google benefit greatly from optimizing this cost. Google’s last project, which focused on the WebP image format, was not very successful, and the company was unable to achieve its goal of replacing the JPG, PNG, and GIF image formats.

Google has decided to take a different approach and improve JPEG instead. To this end, the company has introduced jpegli. jpegli is a JPEG coding library that includes an encoder and decoder. Its encoder and decoder are compliant with the original JPEG standard and its conventional 8-bit formalism. In fact, images encoded using jpegli are compatible with existing decoders in your browser or image viewer.

According to Google’s press release, jpegli compresses images about 35% more than traditional JPEG codecs while maintaining quality. This will increase online bandwidth capacity. Google itself can free up a lot of Google Photos space by re-encoding user content.

Another important feature of jpegli is that it appears to perform more accurate calculations and more effective visual processing, resulting in sharper images with fewer visual artifacts.

The speed of jpegli is similar to other coding libraries, so there is no additional cost or overhead. Google has published the jpegli source code on GitHub and anyone can review it.


Benefits of jpegli:

  • Reduces image size by 35%
  • Maintains image quality
  • Increases online bandwidth capacity
  • Frees up storage space
  • Produces sharper images with fewer visual artifacts
