== 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.
