Why do I need to encode HTML entities?

Characters like , &, and " have special meaning in HTML syntax. Encoding them into entities prevents them from breaking document structure or creating XSS vulnerabilities.

What is the difference between named, decimal, and hex entities?

Named entities use friendly names (©), decimal entities use ASCII/Unicode character numbers (©), and hex entities use base-16 representations (©).

Can this tool decode accented letters (é, ü, ñ)?

Yes! It handles all standard ISO-8859-1 and Unicode accented character entities (é, ü, ñ).

Does decoding affect normal text without entities?

No. Regular text without ampersands and semicolons passes through unmodified.

Is my data transmitted to any external server?

No. The conversion is performed purely via client-side JavaScript in your browser.
