-
jpegoptim, which can be installed from the official jpegoptim repository
-
OptiPNG, which can be installed from sourceforge.net
Or install the utilities via homebrew:
$ brew install optipng jpegoptim
Then add this line to your application's Gemfile:
gem 'carrierwave-imageoptimizer'
And then execute:
$ bundle
Or install it yourself as:
$ gem install carrierwave-imageoptimizer
To add image optimization to your CarrierWave uploader, first include the module:
class MyUploader < CarrierWave::Uploader::Base
include CarrierWave::ImageOptimizer
...
end
Then apply to all versions via:
class MyUploader < CarrierWave::Uploader::Base
...
process :optimize
end
Or to a single image version via:
class MyUploader < CarrierWave::Uploader::Base
...
version :thumbnail do
process :optimize
end
end
Pass an optional quality
parameter to target a specific lossy JPG quality level (0-100), default is lossless
optimization. PNGs will ignore the quality setting.
class MyUploader < CarrierWave::Uploader::Base
...
version :thumbnail do
process optimize: [{ quality: 50 }]
end
end
Pass an optional quiet
parameter to compress images without logging progress.
class MyUploader < CarrierWave::Uploader::Base
...
version :thumbnail do
process optimize: [{ quiet: true }]
end
end
