Encode special characters into HTML entities safely.
About HTML Entity Encoder / Decoder
The HTML Entity Encoder/Decoder translates special characters into safe HTML entities, preventing cross-site scripting (XSS) and formatting issues.
How to use
Input your raw text or HTML snippet. The encoder converts characters like <, >, and & into their respective entities (<, >, &), while the decoder reverts them back.
Why use this tool?
Escaping HTML is a fundamental security practice. Doing it locally provides a quick, secure way to prepare user input or code snippets for safe display on web pages.
Frequently Asked Questions
Why do I need to encode HTML entities?
Unescaped HTML characters like < and > can break page structure or allow XSS (Cross-Site Scripting) attacks. Encoding them into < and > makes them display safely as text.
Which characters get encoded?
The tool encodes the five critical HTML characters: < (<), > (>), & (&), " ("), and ' ('), as well as extended Unicode characters on request.
Can I use this to sanitize user input for a database?
HTML encoding is for safe display in browsers, not database sanitization. For database security, use parameterized queries or a dedicated sanitization library on your backend.
Is HTML Entity Encoder / Decoder free to use?
Yes, HTML Entity Encoder / Decoder is completely free to use with no account, subscription, or hidden fees required — ever.
Does my data get uploaded to a server?
