Thumbnail still produces 300dpi images when Auto (Web optimized) option is selected


Hello, folks

I’m using pimcore 5.4 and I have image asset with 300 dpi quality. I want to use this image in print documents as thumbnail with 300 dpi and in web/newsletters as thumbnail with 72 dpi quality. I’ve created a thumbnail config for web and set Format to Auto (Web optimized - recommended), but it keeps generating thumbnails with 300 DPI

Could you help me with that?
Thank you!
