About HTML Entity Encoder/Decoder
The HTML Entity Encoder/Decoder converts special characters like <, >, &, and " to their HTML entity equivalents (<, >, &, ") and decodes entities back to readable text. Handles both named and numeric entity formats.
Web developers use HTML encoding to safely embed user-generated content in HTML pages, prevent XSS (cross-site scripting) attacks, display code snippets in web pages, and sanitize content for CMS platforms.
All encoding and decoding runs locally in your browser. No data is transmitted to any server, making it safe for processing API responses, code examples, and any content containing sensitive markup.
Frequently Asked Questions
What characters get encoded?
The main characters encoded are < (→ <), > (→ >), & (→ &), " (→ "), and ' (→ '). Other special characters with HTML entity equivalents are also handled.
Why is HTML entity encoding important?
Encoding prevents browsers from interpreting special characters as HTML markup. Without it, a < in user content could break your page layout or enable XSS attacks.
Does the decoder support both named and numeric entities?
Yes. The decoder handles named entities (like &, <) and numeric entities (like &, <) in both decimal and hexadecimal formats.
Can I chain multiple encode/decode operations?
Yes. Click 'Use output as input' to feed the result back and apply additional encode or decode passes — useful for double-encoded content.
Is my data sent to any server?
No. All processing happens locally in your browser using JavaScript. Your text never leaves your device.
