Google biscuit: A biscuit that reduces the storage size of JPEG images by 35%

Google Guetzli JPEG Encoder 35% smaller files with good quality, reduce JPEG size make them smaller, maintain quality, fewer artifacts

Not quite a week ago, Google released a new tool called Biscuits presented; this is an encoder for JPEG files whose memory size should be reduced with as little loss of quality as possible. By the way, Guetzli [guɛtsli] is Swiss German and means Keks. According to Google, Guetzli is the in-house encoder Braid not dissimilar to which one makes PNG and gzip files smaller without the need for a new file extension. In addition, the biscuit should stand out from RNN-based image compressors as well as from RAISR and WebP.

The second example image in the blog entry of the Google Research Team: 20 x 24 pixel graphic showing the eye of a cat. Not compressed (left), libjpeg compressed (middle, lots of artifacts), and compressed by cookies (right, fewer artifacts).

More possibilities and better performance for webmasters

Webmasters should save memory and upload time with Guetzli, which should come along as an open source tool. In addition, photographers can compress their images for the web without having to worry about too much loss of quality. With the same image size, the new encoder for JPEG or JPG files should save around 35% of storage space. Even better than in the picture above, you can see the comparatively few artifacts at Guetzli in compressed images on this graphic:

Perhaps the new open source encoder will finally lead to a usable WordPress plugin that automatically reduces photos for bloggers or for useful Mac apps that use drag & drop to reduce images with good quality. A plug-in for Photoshop would also be desirable in order to output images directly in the corresponding coding.

Faster loading times, better images, less mobile data consumption

But users should also benefit from the new encoder from Google. If the page creator or photographer has to compress his images for a specific web service, then a high level of quality is retained. In doing so, however, the file size and, accordingly, the loading times and, in the case of mobile Internet use, the data volume used decrease. The new JPEG encoder should therefore bring numerous advantages.

I am curious to see if and how Guetzli will change or improve the use of JPEG on the web. What do you think of the new Google tool?
