Emoji Settings is a free WordPress plugin that allows users to control the emoji conversion feature within their site. By enabling or disabling this option, users can prevent the automatic transformation of ASCII smilies, such as :) and :D, into images. Additionally, it stops the conversion of real emojis into Twemoji images, thus maintaining the original appearance of emojis. This can be managed easily from the 'Settings > Writing' section of the WordPress admin dashboard.

The plugin is designed with a WordPress.com-like environment in mind, ensuring that it does not alter standard WordPress behavior. Moreover, Emoji Settings addresses character encoding issues for sites installed with WordPress 4.2 or earlier, and it removes emoji conversions in the admin area, including post titles. Users can also contribute translations through the plugin's sidebar.
