Optimizing Images and Media

Images and media can significantly impact your Magento 2 store's performance. Optimizing them can improve loading speed and create a better user experience.

Optimizing images and media for Magento 2 store

Here are some strategies to optimize images and media:

1. Using an Image Optimizer to Compress Images

Large image files can slow down your website. Compressing images reduces their file size without sacrificing quality.

Use an image optimizer tool, like TinyPNG or ShortPixel. Compress your images before uploading them to your store. This will help your pages load faster.

2. Implementing Lazy Loading for Faster Page Rendering

Lazy loading is a technique that only loads images when they become visible on the user's screen. In this way, the browser doesn't have to load all images simultaneously. It helps to speed up page rendering.

To implement lazy loading in your Magento 2 store, follow these steps:

  • Install a lazy loading extension from the Magento Marketplace.

  • Configure the extension according to your needs and preferences.

  • Test your website to ensure the lazy loading is working correctly.

3. Converting Images to WebP Format

WebP is an image format developed by Google. It provides better compression and quality than JPEG and PNG.

Converting your images to WebP can reduce file sizes and improve loading speed. To convert images to WebP, follow these steps:

  • Install a WebP converter extension from the Magento marketplace.

  • Configure the extension to convert your images to WebP format automatically.

  • Test your website to ensure the WebP images are displaying correctly.

Reducing HTTP Requests

Eliminating the number of HTTP requests in your Magento 2 store improves its performance. Fewer requests mean faster load times and a better user experience.

Reducing HTTP requests for Magento 2 optimization

Here are two strategies to reduce HTTP requests:

1. Merging and Minifying JS/CSS Files

JavaScript and CSS files can increase the number of HTTP requests, slowing down your website. Merging and minifying these files can reduce requests and improve performance. Here's how:

  • Merge JS and CSS files: In the Magento 2 admin panel, navigate to Stores > Configuration > Advanced > Developer.

  • Go to the "JavaScript Settings" and "CSS Settings" sections. Set "Merge JavaScript Files" and "Merge CSS Files" to "Yes."

  • Save the configuration.

Minify JS and CSS files

In the same Developer settings, set "Minify JavaScript Files" and "Minify CSS Files" to "Yes." Save your changes. Clear the cache, test your website, and check if it works correctly.

2. Implementing Critical CSS for Prioritized Loading

Critical CSS is a technique that prioritizes loading the most important CSS rules first, improving the perceived load time for users. To implement essential CSS, follow these steps:

  • Identify the critical CSS rules: Use a tool like CriticalCSS or Penthouse to find the essential CSS rules for your website's above-the-fold content.

  • Extract the critical CSS. Copy the critical CSS rules and place them in a separate file. Or you can inline them in the head of your HTML document.

  • Load the remaining CSS asynchronously. Use the preload attribute or a script like loadCSS to load the rest of your CSS files asynchronously. It prevents them from blocking page rendering.

3. Advanced JS Bundling

To speed up a Magento website, it's essential to use Advanced JS Bundling. It helps to reduce the number of requests made to the server and decrease the size of JS files.

With Advanced JS Bundling, you don't need to load all the bundles for every page a browser requests, just the ones needed for that page.

To enable Advanced JS Bundling, you must define bundles by page type or purpose. Reduce the requests to store configuration advanced developer javascript settings.

Only specific bundles will be loaded for each page. It significantly increases your Magento website's speed. However, you may need professional configuration for complex websites to ensure optimal performance.

Third-party Extensions

While extensions and third-party tools can add helpful features to your Magento 2 store, they can also slow down its performance. Evaluating the impact of these tools and removing or replacing slow ones help improve Magento speed.

1. Evaluating the Performance Impact of Extensions

Evaluating extensions and third-party tools for Magento 2

To assess the performance of your Magento extensions, follow these steps:

  • Monitor your website's performance. Use tools like Google PageSpeed Insights or GTmetrix to measure your site's speed and identify bottlenecks.

  • Compare results Analyze the difference in performance after disabling each extension. Identify which ones are causing slowdowns.

2. Removing or Replacing Slow Extensions

Once you have identified slow extensions, consider the following options:

  • Remove unnecessary extensions If an extension is not essential to your store's functionality, consider removing it. Navigate to Stores > Configuration > Advanced > Advanced. Set the relevant attachment to "Disable." Save your changes and clear the cache.

  • Look for alternatives If an extension is necessary but slow, search for alternative extensions that offer similar functionality but with better performance. Before installing a new plugin, read reviews well. Check its compatibility with your Magento 2 version.

  • Optimize the extension If you cannot find a suitable alternative, contact the extension developer for help with optimization. Consider hiring a Magento expert to optimize it for you.
