Minifier for Magento 2 is designed to compress graphic elements reducing their size (Mb) thereby boosting site speed with no impact on overall image quality. The image compression can be performed automatically and manually. Automatic optimization is activated regularly with the support of Cron running. In case Admin wants to control the process and start optimization at some particular time, he/she can perform it manually. While preparing for the compression procedure, Admin should specify several options: Choose the type of compression - Lossy or Lossless. Select whether or not to convert files to JPG. Tick to compress only published products if needed. Skip previously optimized images, so that Minifier will not touch your compressed images and avoid double charge. Optimize file names automatically to achieve higher search engine rankings.
