Online HTML Entity Encoder & Decoder
Safely convert reserved special characters into HTML entities or decode escaped HTML back into plain text.
Understanding HTML Entities and Web Escaping
In HTML documents, certain characters are reserved by the language parser. For example, the less-than symbol (<) signals the beginning of an HTML tag, while quotes (") define element attributes. If you want a browser to display raw code on a webpage rather than executing it, you must convert those reserved characters into HTML Entities.
Our free Online HTML Entity Encoder & Decoder converts sensitive symbols into safe entity strings (such as < or >). This ensures your code snippets display cleanly on screen while protecting your web applications against Cross-Site Scripting (XSS) vulnerabilities.

Frequently Asked Questions (FAQs)
What is an HTML Entity?
An HTML entity is a string starting with an ampersand (&) and ending with a semicolon (;) used to represent reserved or special characters safely in HTML documents.
How does HTML entity encoding prevent XSS attacks?
By escaping special characters like < and > into < and >, the browser renders the untrusted text harmlessly on screen instead of parsing it as executable JavaScript.
Is my text uploaded to remote servers?
No. All parsing runs client-side inside your web browser session using JavaScript. Your input text remains private.
Is this HTML Entity tool free?
Yes, MicroToolStack's HTML Entity Encoder & Decoder is completely free with no usage limits or sign-up required.
