About

This repository contains the ruby library which adds file processor to compress JPEG images uploaded using the paperclip and kt-paperclip gem.

Add this line to your application's Gemfile:

gem 'paperclip-mozjpeg'
# or 
gem 'kt-paperclip-mozjpeg'

# To use bundled binaries of MozJPEG 3.0 for Mac OS X, Linux and Windows add:
gem 'mozjpeg'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paperclip-mozjpeg
# or
$ gem install kt-paperclip-mozjpeg

To install bundled binaries (must require 'mozjpeg' if not using bundler):

$ gem install mozjpeg

class User < ActiveRecord::Base
  has_attached_file :avatar, :styles => {
    :tiny => {
      geometry: '190x190>',
      mozjpeg_options: '-quality 30', 
    },
    :large => {
      geometry: '1280x1280>',
      mozjpeg_options: '-quality 70 -quant-table 2 -notrellis',
    }
  },
  processors: [ :thumbnail, :mozjpeg ]
end

If you don't want to use the mozjpeg gem bundled binaries and want to specify the path to mozjpeg (cjpeg) or it is not in the PATH use the mozjpeg_path option.
