Google has always been strict in terms of speed of a website and yet takes another step to make the web faster. There are number of tools and services already available for the webmasters or developers to help tweak their website speed and Google on Thursday, launched an latest open source encoder, Guetzli.
A while ago, Google introduced the concept of Accelerated Mobile Pages (AMP), which adds some strict rules to the HTML and it made the mobile browsing blazing fast. At first, only some of the big media websites used this concept, but, later most of the website started using it.
Image size has always been a matter of concern, as it increases the overall page size of any blog or website, which makes web page slower to load. Google has already released some image compression tools and Guetzli is the latest open source encoder.
What is Guetzli?
According to Google, “Guetzli, a new open source algorithm that creates high quality JPEG images with file sizes 35% smaller than currently available methods, enabling webmasters to create webpages that can load faster and use even less data.”
The advantage of Guetzli is that it does not changes the format of the image and let it remain compatible for most of the browser and applications that exists.
Guetzli consumes significantly more time to compress the JPEG images than other encoders, but slower compression seems to be quite worthy, because of the speed gains at the time of loading it and comparably better image quality.
Page loading speed is one of the most crucial Google ranking factor and sometimes images truly requires encoders like Guetzli to make them smaller in size without sacrificing the image quality, so that the web pages could load faster.
