Google decided to implement a new JPEG encoder called Guetzil to avoid situations when the text of a website becomes smutched with stray pixels. This usually happens because of the JPEG file format which can compress graphics in such a way that they load faster on PCS and consume less of the monthly data plan of users’ smartphones.
The new JPEG encoder is bound to be revolutionary
A lot of big companies have been doing their best to do better. RAISR, Google’s WebP, and Microsoft’s JPEG XR have been tried lots of means to change this situation. Nevertheless, their success has been obstructed by the pervasiveness of JPEG support. Now, Google believes that they discovered a better method which could help them compress JPEG.
On March 16, the research released revealed some details about the technology called Guetzli. This new technology is meant to reduce JPEG file sizes by 35% during its testing process. The purpose is not to replace JPEG, but alter its settings to diminish the probability of problems occurring whenever files are compressed. Even if decreased file sizes may appear an arcane technology concern, they are crucial for websites which need to load fast.
This technology can comprise a JPEG file size by 35%
Based on the data released by the HTTP Archive, a usual web page has increased from approximately one megabyte 5 years ago to about 2.5 megabytes nowadays. However, bigger web pages load slower. Users would be happier if the web page they are accessing could load faster. The internet speed indicates that users are bound to buy more things online, spend more time on social media sites and read more news and stories.
To boost the speed of Google’s Guetzli, scientists have designed a test known as Butteraugli which was built to alter human vision. This JPEG compression works by gathering in one place data which we will not notice that is missing. The purpose of Butteraugli is to test several compression settings. Guetzli plays with two different parts of JPEG compression. The first one is discrete cosine transform, which controls how details are recorded.
The second one is quantization, which decides which colors are conserved and which ones are used to cut file size. Researchers from Google stated in a research paper that Butteraugli accounts for properties of vision which are not used by most JPEG encoders. The new JPEG encoder Guetzil works by designing several candidates of compressed JPEGs.
