If you’re architecture an app or site that stores, manipulates or serves a lot of images, you’ll want to accede implementing Google’s new image compression algorithm, which promises to reduce JPEG file sizes by 35 percent more than other methods.

It’s called Guetzli, and it works with absolute browsers and image processing tools. Google says it allows for small file sizes after compromising much on image affection by targeting what’s known as the quantization stage of the compression process, which is where algorithms can squish files but end up with poorer affection images.

However, it’s worth noting that Guetzli is slower than other options out there. Its psychovisual model “approximates color acumen and visual appearance in a more absolute and abundant way than what is accessible by simpler color transforms and the detached cosine transform,” and the search algorithm that Guetzli uses to accomplish this is slower than alternatives like libjpeg.



In the examples above, you can see the uncompressed aboriginal image on the left, libjpeg in the middle and Guetzli’s result on the right; notice how Google’s band-aid has less campanology artifacts in both examples.

The JPEG encoder is open-source and accessible for you to download and apparatus in your own projects from this GitHub repository.
