Google Guetzli, the JPEG encoder that reduces file sizes by 35%

By TechNadu Staff / March 17, 2017

Google announced a new open source algorithm named ‘Guetzli’, that will reduce the JPEG image file size by 35%. And the new JPEG’s is completely compatible with an existing browser, photo editing apps, and the JPEG standard.

Guetzli, which is a cookie in Swiss German. This new JPEG encoder for digital image and web graphics enable faster online experiences by producing the small size JPEG file and this file still maintaining the compatibility over other browsers.

Psychovisual model in Guetzli is based on the human visual processing system. And the visual quality in JPEG image is directly correlated with multi-stage compression process- which are color space transform, discrete cosine transform, and quantization.

Guetzli mainly targets the quantization where you will get a more visual loss, finally, as a result, you will et a smaller size.

The primary use of this new search algorithm is to reduce the JPEG file size and can use to increased the perceived quality of JPEGs while keeping the same file size.

The new JPEG encoder is open source one and it is freely available to download and implement it.
