optimize is a wrapper around various file size optimization tools. It currently losslessly optimizes these mime types:
- application/javascript
- application/x-virtualbox-vdi
- image/gif
- image/jpeg
- image/png
- image/x-apple-ios-png
- text/css
- text/html
optimize relies on these tools (depending on the mime types you like to optimize): gifsicle, jpegoptim, optipng, VBoxManage, yui-compressor
If you like to optimize images:
sudo apt-get install gifsicle jpegoptim optipng
If you like to optimize CSS and JavaScript:
sudo apt-get install yui-compressor
If you like to optimize Virtual Disk Images (VDI):
sudo apt-get install virtualbox
