HTML Encode / Decode
Need to display raw code on a webpage without the browser executing it? Our free HTML Encode/Decode tool safely escapes special characters into standard HTML entities.
What is the HTML Encode / Decode - Escape HTML Entities?
The HTML Encode/Decode tool is a developer utility that prevents the web browser from interpreting text as executable HTML code. It converts characters like `<` and `>` into safe text entities like `<` and `>`.
How to use the HTML Encode / Decode - Escape HTML Entities
- Select 'Encode HTML' or 'Decode HTML'.
- Paste your raw code or escaped text into the input area.
- The tool instantly processes the text and displays the safe output.
- Copy the result to use in your codebase.
Example
If you want to display the text '<b>Bold</b>' on a website, encoding it changes it to '<b>Bold</b>'. The browser will now display the tags visually instead of actually bolding the word.
Understanding Your Results
The encoded result is completely safe to inject into an HTML document or database. It protects your layout from breaking and secures your site against basic injection attacks.
Common Use Cases
- Blogging: Displaying code snippets or tutorials on a tech blog without the browser running the code.
- Security: Sanitizing user input before saving it to a database to prevent Cross-Site Scripting (XSS) attacks.
- Data Scraping: Decoding messy, scraped text data that is filled with `&` and `"` entities back into readable text.
How it Works
The encoder scans the input for reserved HTML characters (primarily `<`, `>`, `&`, `"`, and `'`). It replaces them with their corresponding HTML entity codes. The decoder does the exact opposite, scanning for entities and replacing them with raw characters.
Tips & Accuracy Notes
- •This tool only escapes reserved structural characters. It does not compress HTML code or remove whitespace (minification).
- •Never trust client-side encoding for security. Always encode/sanitize user input on your backend server as well.
Frequently Asked Questions
What is an HTML entity?
An HTML entity is a piece of text (starting with an ampersand & and ending with a semicolon ;) that represents a specific character, ensuring the browser doesn't confuse it for an HTML tag.
How does encoding prevent XSS?
If a hacker submits a malicious `<script>` tag in a comment form, encoding it changes the brackets to text entities. The browser then treats it as harmless text rather than executing the harmful script.
