What is an HTML Escape Tool?
In web development, certain characters have special meaning in HTML, such as the less-than sign (<) and greater-than sign (>) which define HTML tags. To display these characters as plain text without the browser interpreting them as code, they must be "escaped" into safe HTML entities (like < and >). This HTML Escape and Unescape tool allows developers, content writers, and security professionals to quickly encode raw code blocks or decode obscured entity strings safely.
How to Encode and Decode HTML Entities
Follow these simple steps to translate your text or code snippets safely:
Select Mode
Choose the "Escape" tab if you want to turn plain code into safe HTML entities. Choose the "Unescape" tab if you need to translate entities back into readable text.
Input Data
Paste your raw text, JSON payload, or code snippet into the input text area. The tool safely handles large blocks of text instantly.
Convert & Copy
Click the action button. The correctly escaped or unescaped text will appear in the output box. Use the convenient copy button to save it to your clipboard.
Key Features
Strict Entity Mapping
Accurately maps quotes, ampersands, and angled brackets to their exact HTML entity equivalents (e.g., ", &) preventing rendering bugs.
Client-Side Security
Your text never leaves your browser. All encoding and decoding operations are executed locally using secure JavaScript logic, protecting your sensitive code.
XSS Prevention Aid
Escaping raw input is a fundamental step in preventing Cross-Site Scripting (XSS) attacks. Use this tool to quickly sanitize payloads during manual testing.
Frequently Asked Questions (FAQ)
Why do I need to escape HTML?
Escaping HTML ensures that characters meant to be read as plain text are not accidentally interpreted by the browser as executable code or markup. This is critical for displaying code snippets on websites and protecting against Cross-Site Scripting (XSS) vulnerabilities.
Which characters are escaped?
The most common characters escaped are the ampersand (&), less than (<), greater than (>), double quote ("), and single quote ('). This tool utilizes strict entity encoding for comprehensive coverage.
Is HTML escaping the same as URL encoding?
No. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits (e.g., a space becomes %20) for safe transmission in web addresses. HTML escaping turns special characters into named or numeric entities (like <) for safe display within an HTML document.
Can I decode obscured XSS payloads with this tool?
Yes, security researchers frequently use HTML unescaping to reveal the true content of an XSS payload that has been encoded with HTML entities to bypass simple Web Application Firewalls (WAFs).
Is this tool free to use?
Yes, this HTML Escape and Unescape tool is completely free, does not require an account, and places no limits on the amount of text you can encode or decode.
