Choose the right resolution for the image (Read the FAQs for more information).Choose the right format for the image (gif, jpg, png) (Read the FAQs for more information).This is a wide subject but the most important things are: Our extension is only the last step in the image optimization that will help you to pass Google PageSpeed Insights and GTmetrix test, it is not the substitution for best practices regarding the preparation of images for the web. Before uploading images to the web (in this case Magento) you need to prepare them. Our extension will NOT change the resolution of the images. However, it will degrade image quality if you use a "lossy" compressor like guetzli. Our extension will NOT change the visual quality of the images if you use jpegtran which is used by default.
Please understand that there is no PHP code we can write that will make previously mentioned utilities work if they are not compatible with your server nor circumvent your server configuration. There is a possibility it will not work for you. It is also highly dependent on a server type and configuration. Warning! Extension relays on third-party utilities (gifsicle, jpegoptim (32-bit only), jpegtran, and optipng). (Please follow configuration and testing instructions.) Warning! Before using our extension on real images, you must test optimization utilities. Use GTmetrix to check your image optimization status. In order to pass the Google PageSpeed Insights test regarding image optimization Google Perceptual JPEG encoder "guetzli" is required. (By default our extension is using jpegtran and there is no change in image quality after optimization.) Guetzli is much slower than jpegran. This means you will lose some image quality. (See user guide for more information.) Be aware of the following: Guetzli is a "lossy" compressor.
However, you need to install guetzli on your server and configure our extension to use guetzli. Image Optimizer is fully compatible with Google Perceptual JPEG encoder "guetzli". (By default our extension is using optimization utilities recommended by Google PageSpeed Insights and GTmetrix.) You can change optimization options even swap utilities used for optimization with the ones you like. If you are an advanced user you will be pleased to know that extension is fully configurable. You can optimize images by clicking a button in Magento Admin or automatically by a configurable cron job. The extension is very easy to install and use. Apptrian Image Optimizer will optimize your images (GIF, JPG, PNG), reducing their file size without losing image quality and speed up your site.
