Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
Please note that the image you’re using should be as close as 1200 x 630 pixels, and the image file format you are using is only between jpeg, gif, or png as per Opengraph Standards.
Here’s a link for more information:

Looking forward to helping you.
i understand 😐 so ‘ill use only jpg
but avif is so usefull
Hello,
AVIF image format is relatively new and can give higher quality and lower file size compared to other formats like jpg or png. However, there are browser compatibility and other support issues that one has to grapple with.
It is best to stick with the open graph standards and avoid any issues with image display.
If you have any questions or need more help, please let us know.
Thank you for choosing Rank Math!
I have the same problem, WordPress Performance Team plugin like “Modern Image Formats” now auto generate avif file. It also leave original jpg file.
I think Rank Math should have a option for auto picking original jpg file, or show original file for picking. Or manual input url.
Hope will solve this problem
You can fix it by yourself, it just very simple line of code. Go to plugin folder>includes>opengraph>class-image.php
In line 627 add, avif to the supported extension.
$extensions = [ 'jpeg', 'jpg', 'gif', 'png', 'webp' ];
to this
$extensions = [ 'jpeg', 'jpg', 'gif', 'png', 'webp', 'avif' ];
It should work, and waiting for Rank Math update their plugin.
Hello,
@lamkieu1, thank you for the input.
