Overview

Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg. Guetzli generates only sequential (nonprogressive) JPEGs due to faster decompression speeds they offer.

--memlimit M

Memory limit in MB. Guetzli will fail if unable to stay under the limit. Default is 6000 MB
