HTML Encoder

Escape raw text into safe HTML entities online for free — instant, live, entirely inside your browser.

Overview

What is an HTML encoder?

An HTML encoder converts reserved characters like <, >, &, and quotes into their HTML entity form, so they display as literal text instead of being interpreted as markup by a browser.

It's a core building block for safely rendering user-submitted content or code samples on a page, and it's one of the simplest, most effective defenses against cross-site scripting (XSS) injection.

Tips

Best practices to keep in mind

A few things worth knowing about HTML encoding before you use it.

Encoding user-supplied text before inserting it into HTML is one of the simplest defenses against cross-site scripting (XSS) — it stops browsers from interpreting angle brackets as real markup.
Use HTML encoding whenever you need to display code samples, tag names, or symbols like < and > as visible text on a page instead of having the browser render them as elements.
The five characters that matter most for safety are &, <, >, ", and ' — encoding just these covers the overwhelming majority of real-world HTML injection risks in practice.
Encoded output looks unfamiliar at first glance (&lt; instead of <) but renders back to the original characters exactly once placed inside an HTML document — nothing is lost in the round trip.

FAQs

Frequently asked questions

Have questions about HTML encoding text? Here are the most common ones our users ask before getting started.

Is this HTML encoder free to use?

Yes, the HTML encoder is completely free with no signup, no usage limits, and no watermarks on the output. It runs entirely in your browser, so there are no server costs passed on to you and no account is ever required to encode text.

Does my text get uploaded to a server?

No. All encoding happens locally in your browser using plain JavaScript string replacement — your text never leaves your device or gets transmitted anywhere. This makes the tool safe to use with private notes or unreleased content.

What does HTML encoding actually do?

HTML encoding replaces characters that have special meaning in markup — such as <, >, &, and quotes — with their entity equivalents like &lt; and &amp;. This lets those characters display as literal text instead of being interpreted as HTML tags or attribute boundaries by a browser.

Why is HTML encoding important for security?

Encoding untrusted or user-submitted text before inserting it into a page is a core defense against cross-site scripting (XSS) attacks. Without encoding, characters like < and > could be used to inject scripts or malicious markup that a browser would then execute as real code.

Will encoded HTML display correctly once placed on a page?

Yes — encoded entities are automatically converted back to their original characters by the browser's HTML parser when the page renders. The visible result on screen looks exactly like the original text; only the raw source contains the encoded entity form.
