Convert special characters to HTML entities and back with our free HTML Encoder & Decoder. Encode characters like <, >, &, and quotes into their HTML entity equivalents to safely embed them in web pages — and decode them back to readable text just as easily.
HTML encoding is essential for web security and proper rendering. Without encoding, characters like < and > in user-generated content can break HTML structure or — worse — enable cross-site scripting (XSS) attacks. Properly encoding HTML entities is a core web development practice.
Why HTML Encoding Matters
- XSS prevention: Encoding user input before displaying it prevents script injection attacks
- Correct rendering: Ensures special characters display correctly in browsers
- XML compatibility: Required for including special characters in XML documents
- Email templates: HTML emails often require encoded special characters
Common HTML Entities
- & → &
- < → <
- > → >
- " → "
- ' → '
