HTML Entity Encoder Online

Updated 2026-07-09

Encode text to HTML entities online for free. Paste any text or HTML and SnapTools converts the reserved characters — <, >, &, and quotes — plus accented letters and symbols into safe HTML entities, instantly and in your browser. Nothing is uploaded.

Encoding output is one of the simplest, most reliable defences against cross-site scripting (XSS): once <script> becomes &lt;script&gt;, the browser shows it as text instead of running it. Use this whenever you need to display untrusted text or code snippets safely on a page.

// how to use

  1. 1 Paste your text or HTML into the input panel.
  2. 2 SnapTools converts reserved and special characters to HTML entities as you type.
  3. 3 Copy or download the encoded output for safe use in HTML.

// examples

Escape reserved characters
Input
<p>Tom & Jerry said "Hi"</p>
Output
&lt;p&gt;Tom &amp; Jerry said &quot;Hi&quot;&lt;/p&gt;
Encode accented characters
Input
café — €5
Output
caf&eacute; &mdash; &euro;5

// faq

It replaces characters that have special meaning in HTML — like <, >, &, and quotes — with their entity equivalents (&lt;, &gt;, &amp;, &quot;), so the text displays literally instead of being interpreted as markup.
Encoding user-supplied text before placing it in HTML is a core defence against cross-site scripting, because it stops the browser from treating the text as executable markup. Always encode untrusted content on output.
Yes. Along with the reserved characters, accented letters and symbols (é, ©, €, —) are converted to named entities where one exists, using UTF-8.
Yes — use the HTML Entity Decoder to turn entities back into plain characters.
No — encoding happens in your browser, so nothing leaves your machine.
