Use this free HTML Encoder and Decoder to convert special characters into HTML entities and turn common entities back into readable text. It is useful for web developers, bloggers, students, and anyone preparing text for an HTML page, code sample, or documentation. Paste text into the box, choose Encode or Decode, and review the output before copying it.
HTML Encoder & Decoder
What Is HTML Encoding?
HTML uses certain characters to define elements and attributes. For example, the less-than sign and greater-than sign surround HTML tags, while an ampersand begins a character reference. When you need to show these characters as text rather than have the browser interpret them as markup, you can encode them as HTML entities. The encoder on this page replaces common special characters with their entity forms.
For instance, the less-than sign can be represented as <, an ampersand as &, and a quotation mark as ". The encoded text can then be displayed as literal text in suitable HTML contexts. Encoding is a formatting step, not a complete security solution for every web application.
What Does the Decoder Do?
The decoder takes common HTML entities and converts them back into the characters they represent. If a text sample contains <h2>, decoding it produces the literal string <h2>. This is useful when reading escaped content, checking snippets, or restoring text copied from a page or data export.
Decoding does not validate the resulting text or determine whether it is safe to insert into a website. Treat unknown or untrusted HTML carefully. If decoded output contains markup or scripts, do not paste it into a live site without reviewing it and following the security practices for your platform.
How to Use This Tool
- Paste or type your text into the Input text box.
- Click Encode HTML to convert special characters into entity references, or click Decode Entities to convert entity references into characters.
- Review the result in the Output box.
- Use Copy output to copy the result when clipboard access is available.
- Click Use output as input if you want to perform another operation on the result.
- Choose Clear all to remove both input and output and start over.
The tool works with paragraphs, short snippets, punctuation, and many ordinary Unicode characters. Large blocks may take longer depending on your device and browser. The result is generated in your browser after the page loads, so your text is not intentionally sent to a separate encoding service by this tool.
Common Uses for HTML Entities
Displaying code examples
Tutorials and documentation often need to show a tag as an example instead of having the browser interpret it. Encoding angle brackets can help display that markup literally in an HTML page.
Preparing text for web pages
Text that includes ampersands, quotation marks, or angle brackets may need appropriate encoding depending on where it will appear. Use the tool to inspect the entity forms and then apply the correct handling for your page or template.
Reviewing escaped content
When data has been exported or copied with entity references, decoding can make the text easier to read. Always check the result, especially if it contains nested entities or content from an unknown source.
Encoding Is Not the Same as Sanitizing
HTML encoding and security sanitization solve different problems. Encoding changes characters into representations that can be displayed as text in a suitable context. Sanitization examines markup against a policy and removes or restricts elements and attributes that are not allowed. A string that is safe to display as text may behave differently if inserted into an HTML attribute, JavaScript, CSS, or a URL.
For websites, use your platform’s context-aware escaping and trusted sanitization tools. Do not rely on a simple character converter as the only protection against cross-site scripting or other injection risks. The correct method depends on where the data will be inserted and how the application handles it.
Frequently Asked Questions
Is this HTML Encoder free?
Yes. It is available on this page without payment or an account.
Can I encode an entire paragraph?
Yes. Paste a paragraph or a longer text sample into the input box and encode it in one operation.
Will encoding remove my text?
No. The encoder replaces selected characters with entity representations. Review the output to confirm it suits your intended use.
Can I decode every possible entity?
The decoder uses the browser’s built-in HTML parsing behavior for entity references. Unusual or malformed sequences may not behave as expected, so check the result when accuracy is important.
Is the result safe to put directly into any code?
No. The right escaping method depends on the destination context. Encoding for HTML text does not automatically make a string safe for JavaScript, CSS, URLs, or every attribute.
Helpful Tips
Keep a copy of the original text before converting it. Check whether your source has already been encoded to avoid accidental double encoding. For example, encoding an ampersand that already belongs to an entity can change how the string appears. If you are preparing documentation, test the final result in a safe preview. For production websites, follow your framework’s documented output-escaping methods and review any user-supplied markup before publishing.
