HTMLエスケープ について

HTML Escape & Unescape converts characters that have special meaning in HTML (&, <, >, ", ') to their HTML entity equivalents, and vice versa. This prevents XSS attacks and rendering issues when displaying user-generated content or code in web pages.

Use this tool when building HTML templates, displaying code in browsers, or preparing content for safe HTML insertion.
