Google: Reducing Up To 35% JPEG File Size and Providing Faster Websites

Speed of the Internet has always been the major issue faced by everyone. Thus, in order to overcome this speed problem, Google has come up with a unique solution. The Internet giant has developed Guetzli—an open source image compression algorithm. This news algorithm by Google is able to reduce size of the JPEG file up to 35%. You must be questioning the image quality after this reduction in size. Right? Need not to worry. Guetzli also takes care of the image quality and the compatibility of the images with existing image editing applications and web browsers.

As said, every coin has two sides. Guetzli comes with some “not so good property” and that is—it takes a bit more time as compared to other available solution for compressing an image. However, obtaining high-quality images along with smaller size for loading of websites with faster speed is worth waiting. Am I right? However, to reduce the file size, Guetzli makes use of Butteraugliuce—a psycho-visual model. This model takes care of the visual masking and color perception.

As per the research of Google, sizes of compressed image files are kept constant. It further mentions that human raters were opting their image despite the libjpeg produced images, apart from the fact that the libjpeg files had same sizes or in some cases a bit larger sizes. Apart from Guetzli, Google has few additional projects such as such Zopfli encoder for reducing sizes of web images. Zopfli encoder produces WebP—a novel image format supporting lossy and lossless compressions—and smaller PNG files. You can obtain Guetzli for free on Github. Photographers, graphic designers, and web developers can try Guetzli free of cost and experience the dazzling work done by Guetzli.
