About this tool
The HTML Entity Encoder converts plain text characters into their corresponding HTML entity codes, such as turning an ampersand into & or a less-than sign into <. It is useful for web developers, content editors, and anyone who needs to safely display special characters, symbols, or reserved HTML characters in a browser without triggering unintended markup or rendering errors.
Reach for this tool when you are pasting user-generated content into an HTML template, writing code examples that include angle brackets, or working with international characters and symbols that could break page structure. It is also handy when you want to embed quotation marks or copyright symbols in HTML attributes and body content without writing entity codes by hand.
How to use it
- Paste or type the text containing special characters into the input field.
- Click the Encode button to convert all applicable characters to HTML entities.
- Review the output field to confirm characters like &, <, and > are encoded correctly.
- Copy the encoded output using the Copy button.
- Paste the encoded text directly into your HTML file, template, or CMS editor.
- Use the Decode option to reverse encoded entities back to readable plain text when needed.
Pro tips
- Encode only the specific characters you need to escape rather than full blocks of text to keep your HTML source readable.
- Named entities like & are more readable than numeric codes like &, but both render identically in all browsers.
