Preserve Code Formatting is a free WordPress plugin designed to ensure that code snippets maintain their original formatting when displayed on a website. This plugin is particularly useful for developers and content creators who need to present code without it being altered by WordPress's default behavior or other plugins. It prevents HTML encoding of text and avoids the modification of preserved code, allowing users to showcase their code accurately.

The plugin works by filtering content in various areas, including post content and comments, while also offering options to preserve whitespace and prevent shortcode processing. Users are advised against using the visual text editor, as it may conflict with the plugin's functionality. Overall, Preserve Code Formatting is an essential tool for anyone seeking to display code snippets cleanly and effectively in their WordPress sites.
