Frequently Asked Questions
What is an HTML Entity?
HTML entities are special codes used to display reserved characters and symbols in HTML.
They begin with & and end with ;.
For example, < displays as the less-than sign (<), and © displays as the copyright symbol (©).
Why should I use HTML entities?
HTML entities are necessary for these reasons:
1. Preventing HTML interpretation: Characters like < and > would otherwise be interpreted as HTML tags.
2. Displaying special characters: Symbols like ©, ®, ™ that aren’t on standard keyboards.
3. Security: Helps prevent XSS attacks by encoding potentially dangerous characters.
4. Compatibility: Ensures characters display correctly across different browsers and systems.
What’s the difference between named and numeric entities?
Named entities like © are easy to read and remember, but not all characters have named entities.
Numeric entities (decimal © or hexadecimal ©) can represent any Unicode character.
Our tool supports decoding all three types.
Is my data processed securely?
Yes. All conversion processing is done entirely in your browser using JavaScript. Your data is never sent to a server, ensuring complete privacy and security. This also means the tool works offline once the page has loaded.
