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
qualityparameter 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
quietparameter to compress images without logging progress.
class MyUploader < CarrierWave::Uploader::Base ... version :thumbnail do process optimize: [{ quiet: true }] end end
