Frequently Asked Questions
Why should I encode HTML entities in my web application?
Encoding HTML entities is a critical security practice to prevent Cross-Site Scripting (XSS) attacks. By converting characters like <, >, and & into their entity equivalents (<, >, &), you ensure that the browser treats them as text content rather than executable HTML tags.
What is the "Extended" encoding option?
The extended option goes beyond basic HTML reserved characters to include a wider range of symbols, mathematical operators, and special characters (like ©, ™, and accented letters). This is useful for ensuring maximum compatibility across different character encodings.
Does this tool decode numeric entities?
Yes. Our decoder handles both named entities (like ©) and numeric entities (decimal like © or hexadecimal like ©), converting them back into their original Unicode characters instantly.
