So, why are you getting this issue? What does it mean? How to solve this image fault and speed up your WordPress site?

Let’s see everything in this post!

Before getting into the details, let me tell you about the Next-Gen image formats.

What Are Next-Gen Formats?

Image formats like JPEG 2000, JPEG XR, and WebP are the next generation formats that offer better compression than the old-school image formats JPEG or PNG.

These superior image compression formats can encode the pictures in an efficient manner without compromising the quality. 

Yes! they have been introduced for faster image downloads, better-looking graphics and consume minimum data consumption.

WPRocket has compared the JPEG & PNG format with WebP format and produced the following results where you can see the considerable size reduction with the next-gen image format – WebP

Advantages

Since they occupy less space, the loading time of your site will be faster and provides the best user experience for your audience which in turn results in higher conversions.

In addition, you can save more bandwidth and reduce the cost spend on your hosting resources.

Limitations

Unfortunately, the browser support for these superior image formats is not universal. Moreover, WordPress CMS  doesn’t support these next-gen image formats.

So, if you upload these advanced images files to the WordPress media library, then you will get the message – “ Sorry, this file type is not permitted for security reasons”

Then, how to use next-gen image format for a WordPress site?

I didn’t know what happened, I only discovered my post wont show image when I shared…. I was disturbed for almost 2 months until an expert found that EWWW IMAGE OPTIMIZER was responsible. It corrupted my image and blocked them from serving on social media.
