Speed is very important factor on the internet. if speed is not sufficient than big size file will not load properly. that means smaller file load very fast and properly compare to big file. To help with that google has created a new JPEG algorithm That will help to load internet image content very quickly.
google has just released a new JPEG encoder called as Guetzli, that can do 2 useful things.
1. Reduce the file size of JPEG image without reduce the quality of file size.
2. Increase the quality of image without increasing JPEG file size.
According to Google, it decrease the file size without hurting the quality of file. The main advantage to use Guetzli is images are still regular in a new format, so they are still compatible in all browser and every application. Guetzli uses a psycho-visual model, called as Butteraugli. it is based on human visual processing system.
Google has also focuses on several other project to reduce Image size on the web, including its zomfli encoder and WebP.
