guetzli − perceptual JPEG encoder
guetzli [flags] input_filename output_filename
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.
−−verbose
Print a verbose trace of all attempts to standard output.
−−quality Q
Visual quality to aim for, expressed as a JPEG quality value.
−−memlimit M
Memory limit in MB. Guetzli will fail if unable to stay under the limit. Default is 6000 MB
−−nomemlimit
Do not limit memory usage.
