Force HTTPS srcset is a WordPress plugin designed to enhance the security of image serving on websites. It addresses the issue of responsive images defaulting to HTTP URLs instead of HTTPS when accessed over a secure connection. This can lead to mixed content warnings and potential security vulnerabilities. The plugin allows users to enforce HTTPS for srcset attributes, ensuring that all images are served securely regardless of the initial protocol used to access the site.

The plugin offers a user-friendly interface with customizable settings, allowing users to choose between forcing HTTPS srcset for all instances or only when accessed over HTTPS. This flexibility makes it suitable for various website configurations and user needs. By utilizing this plugin, website owners can improve their site's security posture and provide a seamless experience for visitors, free from mixed content issues.
