Hi @angeldavo,
Thank you for your message.
First of all, please do not use two plugins for the same thing. Please choose one image optimization plugin.
Some images may not be available in WebP format because when converted to WebP, they weigh no less than the original file. These are limitations of the WebP format that appear with small images or when the images have been previously optimized.
In this situation, it is better to convert the images to the AVIF format.
I recommend you to try the AVIF format on your website. Images converted to the AVIF format on your website will weigh about 50% less than images converted to WebP only, maintaining even better image quality. This will further improve the performance of your website.
Best,
Mateusz
