HTML Escape & Unescape: The Essential Online Tool for Code Safety

Q: What is the basic purpose of HTML Escaping?

The main purpose of HTML Escaping is to convert special characters (like ) into code-safe text so the browser treats them as literal symbols instead of executing them as HTML tags. This is essential for safe display of user-supplied content.

Q: What does "Escape HTML" actually do to my code?

Escaping HTML replaces special characters with their equivalent HTML entities (for example, the less-than sign becomes &lt;). This makes code safe to publish as text within a web page rather than being interpreted by the browser.

Q: Why would I use "Unescape HTML"?

Use Unescape HTML to reverse the escaping process. If you have text containing HTML entities (like &lt;), the tool converts them back to the original characters (like <) so the content can be rendered or edited as actual markup.

Q: Which characters are considered "special" and need escaping?

The most critical characters to escape are ampersand (&), less-than ( ), and quotation marks (", '). These characters control HTML structure and must be escaped when outputting untrusted content.

Q: What is an HTML Entity?

An HTML Entity is a sequence that represents a character in HTML. It typically starts with an ampersand (&) and ends with a semicolon (;), for example &lt; for , allowing special characters to be displayed safely.

Q: Is using this tool a form of encryption?

No. HTML Escaping is not encryption. It is a reversible translation that makes characters safe for display in HTML. It does not hide or protect the content from being read.

Q: What is Cross-Site Scripting (XSS), and how does escaping prevent it?

Cross-Site Scripting (XSS) is an attack where malicious code (often JavaScript) is injected into a website. Escaping neutralizes XSS by converting harmful tags such as into harmless text ( becomes &lt;script&gt;), preventing the browser from executing the injected code.

Q: Should I escape everything I put on my website?

No. Escape only content that originates from untrusted sources (user comments, form inputs, external APIs). Your site’s own trusted HTML should remain unescaped so it can render and function correctly.

Q: Can I escape JavaScript code?

Yes. If you want to display JavaScript code as an example (so it appears as text, not executed), you must escape it so the browser treats it as content rather than runnable script.

Q: Does this tool support special foreign characters (Unicode)?

Yes. Modern HTML uses UTF-8, and this tool handles Unicode characters (accented letters, non-Latin scripts) correctly, encoding them as needed while preserving content when unescaped.

What is HTML Escaping, and Why is it Necessary?

HTML Escaping is the process of converting characters that have special meaning in HTML—like the less-than sign (<), the greater-than sign (>), and the ampersand (&)—into their equivalent HTML Entities (also known as character references).

The Problem: When Code Becomes Content

In a standard HTML document, the browser interprets text enclosed in angle brackets (< and >) as a tag (e.g., <h1>, <body>, <script>).

If a user were to submit raw HTML, such as <h1>Hello!</h1>, into a comment box on your website, you wouldn’t want the browser to render it as a large heading. You want it to display the literal text string <h1>Hello!</h1>.

More dangerously, if a malicious user inserts a <script> tag, they could potentially execute harmful code in the browsers of other visitors—a vulnerability known as Cross-Site Scripting (XSS).

The Solution: Using HTML Entities

HTML Escaping converts these special characters so the browser treats them as plain text symbols rather than executable code.

Character	Special Meaning	HTML Entity (Escaped Value)
< (Less Than)	Start of a tag	`<`
> (Greater Than)	End of a tag	`>`
& (Ampersand)	Start of an entity	`&`
“ (Double Quote)	Attribute value delimiter	`"`
‘ (Single Quote)	Attribute value delimiter	`'` or `'`

When a browser encounters <script>, it displays the literal text <script> instead of attempting to run the script. This is the foundation of safe HTML display.

When to Use It:

You are capturing user comments, forum posts, or any text input that will be displayed on your site.
You are inserting a snippet of code (like JavaScript or HTML examples) into a blog post and need the browser to display the code, not run it.
You are setting up templates and need to pass dynamic content safely.

Step-by-Step:

Paste the raw HTML or text (e.g., <a href="test">Click me</a>) into the input field.
Click the Escape HTML button.
The result will be the safe, entity-encoded string (e.g., <a href="test">Click me</a>).
Use the Copy button to grab the escaped text.

2. Unescape HTML (Entities $\rightarrow$ Readable Code)

Use this function to reverse the process, translating HTML entities back into their original, functional characters.

When to Use It:

You are retrieving data from a database that has been entity-encoded and now needs to be rendered as live HTML (only if you trust the source!).
You are debugging a piece of code and need to see the original HTML markup after it was processed by a server or CMS.
You need to convert an encoded string back to its original code for editing in an IDE.

Step-by-Step:

Paste the HTML entity string (e.g., The title is "My Book") into the input field.
Click the Unescape HTML button.
The result will instantly revert to the original characters (e.g., The title is "My Book").
The tool includes a live preview feature to help you visualize the final output before using it.
