Frequently asked questions
What is an HTML entity?
An HTML entity is a snippet of text that begins with an ampersand and ends with a semicolon. It represents reserved markup characters or invisible symbols so browsers display them as text rather than code.
Why do I need to encode HTML characters?
Characters such as the less-than and greater-than signs are reserved by HTML for tag syntax. Encoding them ensures browsers render the literal characters instead of parsing them as HTML tags.
Is this HTML entity encoder decoder free?
Yes, this tool is completely free to use with no account creation or subscription required.
Does this tool send my data to a server?
No, all encoding and decoding operations run locally within your web browser. Your data never leaves your device.
What is the difference between named and numeric entities?
Named entities use readable names, such as & for an ampersand, while numeric entities reference character codes using decimal or hexadecimal numbers, such as & or &.
