Free HTML Encoder
Pasting raw HTML into a page makes it render instead of display — encoding fixes that. The HTML Encoder converts <, >, &, quotes and more into safe entities, with a live preview showing the result as text. Choose named entities for readability or numeric entities for maximum compatibility when embedding code samples in blogs, docs, or CMS content.
How to Use the HTML Encoder
- Choose named or numeric entity encoding.
- Paste your HTML into the input box.
- The escaped output appears live.
- Copy it to safely embed code in a page.
Features
Named and numeric entity modes; live encoding; rendered-as-text preview; copy button.
Benefits & Use Cases
Embed code examples in articles, safely display user content in prototypes, prepare snippets for CMS editors that strip raw HTML, or teach HTML without the browser eating your examples.
Tips
Encoding output is a key defense against cross-site scripting (XSS) — but real apps should encode server-side or via framework auto-escaping, not rely on a manual tool.
Frequently Asked Questions
What is HTML entity encoding?
It is replacing characters that have special meaning in HTML — like < and & — with entity references such as < and &, so browsers display them as text instead of interpreting them.
Named vs numeric entities?
Named entities (&) are readable; numeric entities (&) work everywhere including obscure characters. Both render identically in browsers.
Does this prevent XSS?
Encoding user output is a core XSS defense, but it must happen consistently in your application code. Use this tool for one-off content, not as your app security strategy.
Why does my code still render as HTML?
You probably pasted the original instead of the encoded output. Copy the encoded version — it should contain < rather than <.
