HTML Entity Encoder / Decoder
Encode or decode HTML entities safely.
Why use our HTML Entity Encoder?
Encode & Decode
Convert special characters to HTML entities (e.g., & → &) or decode entities back to readable characters.
Prevent XSS
Properly encoding user-provided content before inserting it into HTML prevents cross-site scripting (XSS) vulnerabilities.
Fully Private
All encoding and decoding is done locally in your browser. Your data is never sent to a server.
Instant Results
Paste your text and see encoded or decoded output immediately — no page loads or button clicks needed.
Frequently Asked Questions
What are HTML entities?
HTML entities are special character sequences used to represent characters that have special meaning in HTML (like <, >, &, ") or characters that are not available on standard keyboards.
When do I need to encode HTML?
Always encode user-generated content before rendering it as HTML. Failing to do so allows malicious users to inject scripts — a vulnerability called Cross-Site Scripting (XSS).
What's the difference between named and numeric entities?
Named entities use a descriptive name (e.g., & for &). Numeric entities use the character's Unicode code point (e.g., & for &). Both are valid and produce the same output.
Does it handle Unicode and emoji?
Yes. Unicode characters and emoji can be encoded to their numeric HTML entity equivalents, ensuring compatibility across all browsers and email clients.
