HTML Entity Encoder / Decoder
Encode and decode HTML entities and special characters
About the HTML Entity Encoder / Decoder
Certain characters carry structural meaning in HTML — the angle bracket that opens a tag, the ampersand that starts an entity reference, the double quote that delimits an attribute value. When those characters appear in content rather than markup, they must be escaped into entity form to prevent browsers from misinterpreting them. The HTML Entity Encoder converts raw text to safe entities in one click, and reverses the operation just as easily.
Web developers use it when building dynamic HTML templates: a product description containing a trademark symbol or an apostrophe needs encoding before it is injected into an attribute value. Content editors use it when a CMS is stripping or mangling characters — pasting the problematic text here shows exactly what entity sequence is needed. Security testers encode angle brackets to demonstrate what a safe-rendered version of a suspected XSS payload looks like versus the raw string.
The tool uses the browser's own DOM for encoding and decoding, which guarantees correct results for named HTML5 entities, decimal numeric references (<), and hexadecimal references (<) alike. A quick-reference table beneath the tool lists the ten most commonly needed entity mappings — the kind you look up so often that having them one scroll away is worth the space.
How to Use the HTML Entity Encoder / Decoder
- Choose "Encode" to convert raw text into HTML entity sequences, or "Decode" to turn entity strings back into their original characters.
- Paste or type your content into the left panel. The output updates instantly in the right panel.
- Click "Copy" above either panel to send its contents to your clipboard.
- Refer to the entity reference table at the bottom for the ten most common special characters and their named, decimal, and hex entity forms.
Why Use ToolForge’s HTML Entity Encoder / Decoder
- Uses the browser's own DOM element internally — the same engine rendering the page — which means the encoding and decoding results match exactly what a browser would produce or expect.
- Handles both encode and decode directions in a single tool, so you do not need to switch between an encoder and a separate decoder site.
- The quick-reference table keeps the most commonly needed entities — angle brackets, ampersand, quotes, copyright, trademark, euro — immediately visible without a separate search.
- Runs client-side with no upload — safe to use with HTML fragments from private internal tools, CMS templates, or email systems.
Frequently Asked Questions
What is the difference between named entities and numeric entities?
Named entities use a human-readable name: < for less-than, & for ampersand. Numeric entities use a decimal (&# followed by a number) or hexadecimal (&#x followed by hex digits) code point. All three represent the same character — named entities are easier to read, while numeric entities work for any Unicode code point, including characters that have no named entity form.
Why do I need to encode HTML entities?
If you inject text containing < or & directly into HTML, the browser parses them as the start of a tag or entity reference rather than as literal characters. This can break your layout or, worse, open an XSS vulnerability if the text comes from user input. Encoding converts those characters to their safe entity equivalents so the browser renders them as visible text rather than treating them as markup.
Does the encoder handle the full Unicode character set?
The encoder outputs the most specific named entity where one exists (like © for ©). For characters without a named entity, it falls back to the raw character because modern HTML5 documents with a UTF-8 charset can include most Unicode characters directly without encoding them.
Is my text data sent to a server?
No. Encoding and decoding use a hidden browser DOM element, which is entirely local to your browser tab. No text is transmitted anywhere.
