LOSSLESS image size reduction for jpg, png and gif in the cloud
- no image libraries needed, everything done in the interwebs
- less size (up to a 97% saving) = faster downloads = less bandwidth + happy users
Install
install ruby + rubygems
sudo gem install smusher
Usage
Optimize a single image or a whole folder:
smusher /apps/x/public/images [options]
smusher /apps/x/public/images/x.png [options]
smusher /apps/x/public/images/*.png [options]
Options: -q, --quiet no output -c, --convert-gifs convert gifs to PNGs --service PunyPng use PunyPng for image optimizing, instead of SmushIt -v, --version display current version
Example
smusher /apps/ts/public/images
smushing /apps/rs/public/images/social/facebook_icon.png
2887 -> 132 = 4%
smushing /apps/rs/public/images/social/myspace_icon.png
3136 -> 282 = 8%
smushing /apps/rs/public/images/dvd/dvd_1.png
5045 -> 4 = 0%
reverted!
...
PunyPng - usage limit
The default Smusher::PunyPng.api_key is used by all users and
could already be full when you try to smush some images.
Create a .puny_png_api_key in your home directory with your own api key from PunyPng.
Protection
Any image that returns a failure code, is larger than before, or is empty will not be saved.
TODO
- only optimize 'new' images -> save time when doing on already optimized folder
JS + CSS
reduce images and minify css + js -> try reduce.
