HTML Entity Encoder & Decoder | Escape Special Characters

Encode <, >, &, quotes, and Unicode characters into HTML entities, or decode entities back into readable text.

Escape Characters for HTML Markup

Encode angle brackets, ampersands, quotes, apostrophes, non-breaking spaces, and Unicode characters so they can be displayed safely inside HTML content.

Decode Entities Back to Readable Text

Turn strings such as &, <, >, ", and numeric entities back into readable text when cleaning CMS content, scraped snippets, templates, or email markup.

When Entity Encoding Matters

Use entity encoding when showing code examples, preserving special characters in markup, checking copied content, or preventing text from being interpreted as HTML tags.

About This Tool

HTML Entity Encoder converts special characters such as < > & " and non-ASCII characters into their HTML entity equivalents, and decodes entity strings back to readable text. It prevents HTML injection when displaying user-submitted content.

When to Use It

Use this when embedding user-provided text in HTML and you need to escape it safely, when debugging HTML that contains double-encoded entities, or when converting typographic characters for HTML compatibility.

How to Use

  1. Select Encode or Decode mode.
  2. Paste your text into the input area.
  3. Click Convert to produce the encoded or decoded output.
  4. Copy the result and use it in your HTML template.

Frequently Asked Questions

Why do I need to encode HTML entities?

Unencoded characters like < and > are interpreted as HTML tags. Encoding them as &lt; and &gt; displays them as text without being parsed as markup.

What is the difference between numeric and named entities?

Named entities like &amp; are human-readable. Numeric entities like &#38; use the decimal character code. Both produce the same result in a browser.

Does encoding prevent XSS attacks?

Encoding output in the HTML context is one layer of XSS prevention. Always encode output in the appropriate context for each insertion point.
