Efficiently encode images
"Efficiently encode images" means that your webpage is using images that are not efficiently encoded, which can slow down your site and negatively impact the user experience.
How to fix it
The solution is to efficiently encode your images. Here's how:
Step 1: Identify Inefficiently Encoded Images
First, you need to identify the inefficiently encoded images. You can use Chrome DevTools for this. Open DevTools, go to the 'Network' tab, and look for images that are larger than necessary.
Step 2: Efficiently Encode Images
Once you've identified the inefficiently encoded images, you need to re-encode them more efficiently. This might involve using a tool like ImageOptim or TinyPNG to reduce the file size without significantly reducing the quality, or converting your images to a more efficient format like WebP.
<!-- Before -->
<img src="large.jpg">
<!-- After -->
<img src="optimized.jpg">
In this example, we've replaced a large image with an optimized version to reduce the file size.
Step 3: Test Your Changes
For an even better solution, consider testing your changes to make sure they don't break any functionality. This can help ensure that your site still works as expected with the efficiently encoded images.
