Free Online HTML Entity Encoder & Decoder Tool
Easily convert special characters into safe HTML entities or decode entities back to readable text instantly in your browser.
Why Use an HTML Entity Encoder and Decoder?
When building modern web pages or managing content management systems (CMS), preventing Cross-Site Scripting (XSS) and ensuring proper browser rendering is critical. An HTML entity encoder translates reserved characters—such as <, >, &, quotes, and accented letters—into safe equivalent numerical or named entities. Conversely, an HTML entity decoder transforms raw entity codes back into readable text for debugging and content management tasks.

Common Use Cases for Web Developers and Content Creators
Frontend developers frequently rely on HTML escaping when dynamically rendering user-generated content or displaying code snippets inside documentation pages. Without proper entity encoding, browsers might mistakenly interpret characters like brackets (< and >) as actual HTML tags, breaking the layout or introducing severe security vulnerabilities. Technical writers and bloggers also use this utility to safely showcase HTML syntax tutorials without executing the actual markup on the live page.
