NAME¶
guetzli - perceptual JPEG encoderSYNOPSYS¶
guetzli [flags] input_filename output_filenameDESCRIPTION¶
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¶
--verbosePrint 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.
