Informations about the package image-optimizer
Image Optimizer
Image optimization and compression tool for the console. This tool optimizes PNG, JPEG and GIF files, using gifsicle
, jpegoptim
, jpegtran
, pngcrush
and pngout
and can usually reduce the filesize by 10% to 70%.
As optimzing images is CPU intensive and it may take several minutes for a larger PNG file, image-optimizer
keeps track of which image files it has optimized. Each image file will only be optimize once, unless the --force
flag is set.
image-optimizer
is intended to be run unattended in a cronjob.
Example Usage
Optimize Images In /path/to/images
image-optimizer --path="/path/to/images"
Optimize Images In /path/to/images
, Ignoring History
image-optimizer --path="/path/to/images" --force
Set All Images In /path/to/images
As Optimized
image-optimizer --path="/path/to/images" --index-only
