Hi there @mateuszgbiorczyk,
kindly allow me to ask more questions. I ran the conversion again and it stopped at 12%. Is the percentage a reference as of how much images were decreased, or does it implicate the overall progress?
Further I’d like to know if it’s normal that my images are still shown with their initial format when inspecting (via console) the website, due to the mod_rewrite method you refer to in your description.
Does the compression/conversion also apply if the website is distributed via CloudFront?
What happens to files that have been rewritten on the server, if I deactivate the plugin, respectively how can I restore the default image files again?
Thank you very much and all the best.
