Fastly Image Optimization in Magento 2 is one of the features helping to speed up loading images on an e-commerce site. This will lead to an improvement in the user experience and the overall site performance. The file size of the images is decreased, but not the quality, by compression, resizing, and changing formats.
Fastly is a CDN, Content Delivery Network, which delivers the content of your website to users more rapidly by making various copies of your website on different servers across the world. When a user visits your site, for instance, it will show them the images from a nearer server.
Magento 2 is a popular eCommerce platform that uses Fastly for automatic image optimization. This includes automatic real-time processing of large images at the time of delivery. There are a set of common techniques that entail resizing images, converting them to the WebP format smaller, faster image format, and lazy loading where images load only when they're visible on the screen.
Fastly Image Optimization gives the opportunity to accelerate your Magento 2 store by serving and delivering images much more effectively, which makes your website faster. This influences the users' experience and perhaps will lead to increased sales.
First, ensure that within your Magento 2 store, there is already a setup of Fastly CDN. Fastly is a tool whose purpose is to deliver content cached copies of images, for example, servers closer to customers in order to load the website faster.
In practice, Fastly will have to be set up by installing the Fastly module in Magento and configuring it using your Fastly account credentials.
Once you have installed Fastly in Magento, log in to your Fastly account where you'll manage all of your Fastly configurations.
Follow this to the Fastly dashboard, where you can have more control over the optimization and delivery of your images.
In the Fastly dashboard, find the setting called Image Optimization. This feature needs to be enabled for the optimization of images in your Magento 2 store by Fastly to begin.
When this option is enabled, Fastly will automatically compress and optimize images without reducing their quality, which will make your website load faster.
You can determine how much image quality you want to sacrifice depending on your preference. Fastly allows you to choose just how much you need to compress your images.
Backing the quality down a little makes the speed better; having too little quality can make the images fuzzy or grainy. A general setting could be around 70-80% quality.
Fastly automatically converts images to the WebP format: a modern, highly optimized image format that loads much faster compared to traditional formats like PNG or JPEG.
To do this, enable the setting called "Image Format Conversion" within Fastly. Fastly will automatically serve a WebP image on browsers that support them. For browsers that do not support WebP, it will still serve the original format.
You can set up rules that would allow resizing of images depending on the device or screen size of your users. For example, mobile users can get smaller-sized, optimized images compared to desktop users, which further improves speed.
In the Fastly settings, You can define what the dimensions-height and width-images are resized to for a variety of screen sizes.
It also caches optimized images, which means that the processed images are stored on servers closer to your customers. This eliminates the need to fetch images from your original server multiple times.
In the Fastly Dashboard, you would configure how long these images should be cached before they need to be refreshed.
After setting everything up, go ahead and head back to your Magento 2 store. Test your website out and see whether your images load fast and their quality is acceptable.
You could see how well optimizing those images works by testing them on something like Google PageSpeed Insights or GTmetrix to check the page load time.
After you set up Fastly Image Optimization, follow up on how your store improves. Fastly provides reports and analytics to show, exactly, how your images are being optimized and how much faster they are being delivered.
