HTML Entity Encoder Decoder

Encode special characters into HTML entities or decode escaped entity strings back into readable text.

Last reviewed: June 11, 2026

About this tool

Escape or unescape HTML entities when cleaning snippets, preparing templates, or debugging encoded content from CMS tools and APIs.

HTML Entity Encoder and Decoder is useful when text needs to move safely between readable characters and escaped HTML entities. It helps with templating, CMS content, snippets, and debugging cases where symbols render incorrectly or need safe encoding.

  • Encodes quotes, angle brackets, ampersands, and apostrophes into safe entities.
  • Decodes entity strings back into normal readable HTML or text.
  • Runs entirely in the browser with no text uploads.

How to use HTML Entities

Paste the input, choose whether you need encoding or decoding, and review the transformed text before copying it into the target HTML or content workflow. When special symbols matter, test the real final string so you can confirm the result matches the rendering context you care about.

When this tool is useful

  • Encodes quotes, angle brackets, ampersands, and apostrophes into safe entities.
  • Decodes entity strings back into normal readable HTML or text.
  • Runs entirely in the browser with no text uploads.

Practical tips

    Examples you can test

    These examples show the kind of real input and reviewed output this tool is designed to support. Use them as a starting point before pasting your own production content, then compare the output with the destination system that will use the result. The goal is not only to produce a value, but to make the input assumptions, output format, and review step clear enough that the result can be trusted in a real workflow.

    Encode unsafe HTML characters

    Example input

    <span>Tom & Jerry</span>

    Expected output

    &lt;span&gt;Tom &amp; Jerry&lt;/span&gt;

    Encoding is useful when showing markup as text instead of letting the browser parse it.

    Decode copied entity text

    Decoding helps review text copied from HTML source, CMS fields, or feeds.

    Validation checklist

    Run through these checks before copying the result into a CMS, codebase, spreadsheet, campaign, support ticket, or production document. Small formatting differences, unit assumptions, hidden whitespace, and platform-specific rules are common sources of mistakes in quick browser tools, so the final review should happen in the same context where the output will be used.

    • Encode text before displaying literal markup inside HTML.
    • Do not decode untrusted input and insert it as HTML without sanitization.
    • Check quotes and ampersands when output will be used inside attributes.

    Why people use this tool

    Searches around HTML entities are usually tied to active implementation problems such as escaping, rendering, or pasted content cleanup. A good page solves that quickly and supports both directions so people can debug what they are seeing on the page.

    Frequently asked questions

    Does this escape the most common HTML characters?

    Yes. It covers the characters most commonly escaped in HTML content and attribute values.

    Can I decode entity strings copied from HTML source?

    Yes. Paste the encoded text and the tool will decode it back into readable characters.

    Does the encoder handle characters outside the Basic Multilingual Plane, such as emoji?

    Yes. Characters above U+FFFF are encoded as numeric HTML entities using their full Unicode code point, so emoji and supplementary characters convert correctly.

    Should I use named entities like &amp; or numeric entities like &#38;?

    Named entities are more readable in source code, but numeric entities have broader parser support. The tool outputs named entities for common characters and falls back to numeric for less common ones.

    Can I paste an entire HTML document for decoding, or only fragments?

    You can paste full documents or fragments. The decoder only transforms entity sequences and leaves all other HTML tags and attributes untouched.
