Encoded/decoed HTML codes will display here...
What Is This Tool?
The Online HTML Encoder converts raw HTML input into encoded HTML entities. It prevents HTML from rendering, preserving the original code format so it can be safely displayed on webpages, content management systems, or documentation without execution.
How to Use This Tool?
- Paste your raw HTML code into the provided textarea input field
- Click the 'Encode' button to transform the HTML elements and special characters into encoded entities
- View the encoded HTML output displayed beneath the input area
- Use the 'Copy' button to copy the encoded result for safe embedding
- You may clear the input field anytime using the clear button to start fresh
Key Features
- Textarea input for pasting any raw HTML code including tags, attributes, and special characters
- Encode button that converts special HTML characters into their corresponding entities
- Clear input button to reset the input area quickly
- Copy output button to easily copy the encoded HTML
- Real-time display of the encoded HTML output in a sanitized, non-rendering format
Examples
- Encoding a snippet like <div class="example">Hello & welcome!</div> into safe HTML entities for display in tutorials
- Converting HTML form code with special characters so it shows as code without submitting or executing
- Embedding HTML samples in blog posts or documentation without the browser rendering the tags
Common Use Cases
- Developers sharing HTML code safely on forums or collaboration platforms
- Bloggers embedding HTML snippets in articles without triggering rendering
- CMS editors needing to preserve HTML code formatting without execution
- Educators demonstrating HTML code examples in tutorials and lesson plans
- Preventing possible XSS vulnerabilities by encoding unsafe HTML in user-generated content
Tips & Best Practices
- Always verify the encoded output before embedding to ensure it displays correctly
- Use this tool when sharing HTML code publicly to avoid accidental rendering
- Combine with site-specific decoding scripts if you require decoding functionality
- Keep source HTML clean and minimal to avoid unnecessary encoding overhead
- Clear the input area regularly to prevent accidental encoding of outdated code
Limitations
- This tool only encodes HTML characters; it does not decode encoded entities back into raw HTML
- It does not validate whether the HTML input is syntactically correct or well-formed
- Strictly performs character encoding and does not handle other sanitization or security measures
- Decoding support must be implemented separately through custom site scripts if needed
Frequently Asked Questions
- Can this tool decode encoded HTML entities back to raw HTML?
- No, this tool only provides encoding functionality. Decoding must be performed by additional scripts or tools.
- Will this encoder validate my HTML code for errors?
- No, it only converts characters to entities and does not check for HTML syntax correctness.
- Why should I use HTML encoding instead of pasting raw HTML?
- Encoding prevents the HTML from rendering in browsers, preserving your code formatting and avoiding unintended execution.
Key Terminology

- Special codes that represent reserved characters in HTML, used to display characters like < or & without rendering them.
- Encoding
- The process of converting characters into HTML entities to prevent them from being interpreted as code.
- Textarea Input
- A multi-line input field where users can paste or type raw HTML code for encoding.
- Sanitized Output
