Hey there @charlotter
Thanks so much for taking the time to review our Smush plugin.
We’re really sorry to hear that there was a noticeable effect after optimizing the images, though, as pointed out by our support team after investigating the issue on your website, it turns out that it was not related to Smush after all as those images were not optimized by the plugin itself.

Did you try the suggestion by my colleague?
In any case, we do hope that your overall experience will change over to a 5-star, and if you need any further help, be sure to let us know.
Best regards,
George
