HTML Entity Encoder / Decoder

Convert special characters to their matching HTML entities to prevent markup execution, or parse entities back to standard tags.

What are HTML Entities?

In HTML, certain characters are reserved (such as < and > which designate the start and end of tag components). If you write these characters inside standard text blocks, the web browser might interpret them as actual tags, breaking your page layout or introducing security risks like Cross-Site Scripting (XSS).

To safely render these characters, you must encode them into safe HTML entity escape characters (like &lt; or &gt;). This tool processes this escaping locally inside your browser, keeping your text strictly confidential.

Frequently Asked Questions

What is HTML encoding used for?

Encoding converts characters like <, >, and & into safe HTML entity representatives like &lt;, &gt;, and &amp;, preventing the browser from executing them as actual code.

Does this tool decode entities?

Yes. You can bidirectionally encode plain text markup or decode HTML entity strings back to their visual character representation.
