Serve Images In Next-Gen Formats Issue

This issue notification means that at least one internal URL on your site contains images in old formats (BMP, JPEG, or PNG).

What Does “Serve Images In NextGen Formats” Mean?

There are old image formats and modern formats. Of course, the new generation formats provide the ability to publish images of better quality. For example, AVIF and WebP are image formats that have excellent compression characteristics.

Encoding pictures in these formats, rather than JPEG or PNG, will cause them to load faster and consume less data. Accordingly, your site will load faster, which will positively impact search engine rankings.

You should get a detailed report with a list of images that you can optimize and thereby increase the speed of your site.

Why is this important?

Obsolete image formats cannot provide good compression and high-quality level as the new generation formats do.

It is positively affecting both the user experience of your site and the indexing process. Images and other content directly affect the site’s loading speed, which is a significant ranking factor. To make sure your site loads faster and heavy content isn’t the cause of slow speed, you need to optimize your pictures. Using JPEG 2000, JPEG XR, and WebP formats gives the site owner the ability to optimize the images on the site.

How to fix the issue?

To fix the issue with serve images in next-gen formats, you require converting the images on your resource to the new WebP format. Search engines recommend using the new popular format displayed by most browsers on mobile devices and desktops. By converting to this format, you can shrink the image by 25-50%.

  1. Use the tool to convert all your images to the new format.
  2. Use Node.js to convert JPEG / PNG images to WebP.
  3. Manage WordPress plugins and .htaccess to optimize and maintain your images.

Despite this issue, you can also use backup versions of JPEG / PNG. It applies if you know there are users whose browsers simply do not support WebP.
