Have you ever copied special characters into your HTML code only to find them break your layout, display incorrectly, or even open security risks?
That’s why using a reliable, client-side HTML entity encoder and decoder tool is essential for web developers, bloggers, students, and anyone working with HTML content.
Whether you’re trying to encode HTML special characters for safe web display, or decode existing HTML entities back into plain text, this tool gives you full control — instantly, securely, and without installing anything.
What Is an HTML Entity?
An HTML entity is a piece of text (a string) that begins with an ampersand & and ends with a semicolon ;. These are used to represent characters that have a specific meaning in HTML.
For example:
<=<>=>&=&"=" = non-breaking space
Without encoding, these characters could interfere with your page’s structure or pose security vulnerabilities.
That’s where an HTML entity encoder comes into play.
Why Use an HTML Entity Encoder / Decoder?
HTML doesn’t allow certain characters to appear directly in code — especially symbols like <, >, &, or ". If inserted raw, they can be misinterpreted as HTML elements or attributes, which can:
- Break the layout
- Expose XSS vulnerabilities
- Cause invalid rendering in browsers
Using an HTML entity encoder tool, you can safely:
- Display special characters inside web pages
- Protect your site from script injection
- Escape content before embedding it inside HTML, XML, or JSON
Likewise, the HTML entity decoder reverses the process — converting entities like < back to < so you can read or reuse plain content.

HTML Entities That Must Be Encoded
Here are the top characters that should always be encoded when included inside HTML documents:
| Character | Entity Code |
|---|---|
< | < |
> | > |
& | & |
" | " |
' | ' |
Other characters like ©, ™, €, and ® also have entity representations like ©, ™, etc.

When Do You Need to Encode or Decode?
Encoding and decoding are essential in these real-world scenarios:
- When embedding text inside HTML tags
- When dynamically injecting content into the DOM using JS
- When storing special characters in databases
- When submitting user input through forms
- When generating safe URLs or query strings
- When working with international characters in multilingual websites

Developer Integration Tips
If you prefer to encode or decode using code, here’s how you can do it in various languages:
HTML Entity Encoding in JavaScript
javascriptCopyEditfunction encodeHTML(str) {
return str.replace(/&/g, "&")
.replace(/</g, "<")
.replace(/>/g, ">")
.replace(/"/g, """)
.replace(/'/g, "'");
}
HTML Entity Decoding in JavaScript
javascriptCopyEditconst decodeHTML = str => {
const textarea = document.createElement('textarea');
textarea.innerHTML = str;
return textarea.value;
};
Python (Using html module)
pythonCopyEditimport html
html.escape('<div>') # Encoding
html.unescape('<div>') # Decoding
These logic snippets are great if you’re building your own html entity encoder for developers or integrating with a CMS.
