The Custom Permalink Editor is a free WordPress plugin designed to enhance your site's URL structure by allowing manual edits of permalinks for posts, pages, and custom post types. It does not alter the default permalink structure of your theme, ensuring that users have control over individual URLs without affecting existing settings. Users can create SEO-friendly URLs by simply editing the permalink box within the post editor, making it easier to optimize for search engines.

This plugin offers additional features such as the ability to exclude specific permalinks or post types from being processed, and it allows for the inclusion of accented letters in URLs. If you choose to uninstall the plugin, your permalinks revert back to the default WordPress structure, ensuring that you maintain control over your site's URL format. With straightforward functionality, it is a valuable tool for WordPress users looking to optimize their website's navigation.
