GUETZLI

NAME

guetzli − perceptual JPEG encoder

SYNOPSYS

guetzli [flags] input_filename output_filename

DESCRIPTION

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.

OPTIONS

−−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.
