ZP Remove Srcset is a free ClassicPress & WordPress plugin that prevents srcset attributes being added to images.
Srcset attributes are automatically added to larger images by ClassicPress & WordPress, to tell browsers which image size to use according to the available resolution. Depending on a site’s purpose this may not always be helpful, hence this simple plugin which prevents the automatic addition of image srcset attributes within post, page and CPT content.
There is no settings page, just activate and you’re done.
