Google Makes New Version of JPEG: More Economical
Morrissey Technology – Google’s attempt to create a new photo format via Webp didn’t seem to be very successful, and finally they decided to create a better JPEG format. As is known, Webp is an image format created by Google which is actually intended to replace JPEG, PNG and GIF. This format was first introduced in September 2010, and the first stable version was only released in April 2018.
However, until now the Webp format still seems to be getting “resistance” from users. As a result, Google chose to modify and make JPEG better, namely using jpegli. Jpegli is a coding library made by Google that contains an encoder and decoder. Both of these can follow the “rules” of the original JPEG standard and most 8-bit formalisms. In other words, all photos encoded using jpegli should be compatible with every existing decoder, such as those in browsers or image viewers on user devices.
Google promises jpegli can compress images 35% more than traditional JPEG codecs but still maintain visual quality. From here alone, the advantages of jpegli are very profitable for online use, because it can save bandwidth.
They also claim jpegli makes photos “clearer and displays fewer artifacts.” It can also encode images in 10+ bits, more than the 8 bits in traditional JPEG.
And, most importantly, jpegli also doesn’t require more computing or processing than traditional JPEG, so FOR4D it shouldn’t — it won’t slow down the photo processing process. Currently, the full version of jpegli source code has been posted by Google on GitHub, so anyone who is interested can try it out for themselves.
