HTML Encoder Online Free — Escape & Encode HTML Entities

HTML encoding converts characters like <, >, and & into entities so browsers render them as text instead of markup. Developers use it when inserting dynamic content into templates, preventing XSS, and debugging escaped strings from CMS exports.

How to encode HTML online

• Paste plain text into the Encode tab — output updates live
• Angle brackets become &lt; and &gt;, ampersands become &amp;
• Switch to Decode to reverse entities back to characters
• Share a link with your team — state is preserved in the URL

Common encoded characters

• < → &lt;
• > → &gt;
• & → &amp;
• " → &quot;
• ' → &#39;

Why use a browser-based encoder

Server-side encoders receive your text on their infrastructure. For user-generated content previews, email templates with client names, or proprietary copy, a client-side tool keeps data on your device.
