Frequently Asked Questions
What are HTML Entities?
HTML entities are sequences of characters used to display reserved characters (like <, >, &) or characters not present in standard character sets (like emojis, math symbols, accents) safely in HTML without breaking browser rendering.
Why should I encode special characters in HTML?
Reserved characters like the ampersand (&), less-than (<), and greater-than (>) symbols carry syntactic meaning in HTML. If they are written as-is, the browser may misinterpret them as code tags, which leads to layout breakage or cross-site scripting (XSS) security vulnerabilities.
Is my input text stored or analyzed?
No. The entire conversion process executes entirely client-side using Javascript inside your local browser. No data is stored, cached, or sent to external servers.
