HTML Entity Encoder/Decoder — Both Directions, Instant
Encode special characters into HTML entities (like & or ') or decode entities back to their original characters — handling named entities, decimal (&) and hexadecimal (&) forms, all three of which appear in real-world HTML depending on what generated it.
How to use HTML Entity Encoder
- Paste your text or HTML entity string.
- Choose encode or decode.
- Copy the result.
Frequently asked questions
- Why do I need to encode characters like < or & in HTML?
- Unescaped < and & have special meaning in HTML markup — a literal < in text content can be misread as the start of a tag, which is exactly what entity encoding prevents.
- What is the difference between named, decimal and hex entities?
- & (named), & (decimal) and & (hex) all represent the same ampersand character — different tools and generators produce different forms, which is why the decoder handles all three.
- Does this help prevent XSS?
- Proper output encoding is one part of preventing XSS, though real protection also depends on context-aware encoding and, ideally, a templating system that auto-escapes by default rather than manual encoding alone.
