What is HTML Encoding?
HTML encoding (or HTML Entity Encoding) replaces special characters that have a specific meaning in HTML (like <, >, &) with safe alternatives called "entities" (like <).
This prevents browsers from executing user input as actual code, effectively preventing Cross-Site Scripting (XSS) attacks. It's also required when you want to display HTML code blocks within a webpage without the browser trying to render them.
Features
- XSS Prevention: Encodes standard dangerous characters like brackets and quotes.
- Live Conversion: Type into the input box and see your results encoded or decoded in real-time.
- Robust Decoding: The decoder intelligently parses standard HTML entities (like
©) securely.
Privacy Note
Your data is fully secure. Since all encoding and decoding is performed locally via client-side JavaScript, your text never leaves your device.
