Frequently asked questions
Questions about HTML Encoder & Decoder
Why should HTML text be encoded?
Encoding prevents characters such as angle brackets and ampersands from being interpreted as HTML markup when they should be displayed as plain text.
Does HTML encoding provide security?
Context-aware output encoding is an important defense against cross-site scripting, but correct protection depends on where the value is inserted. HTML text, attributes, URLs and JavaScript require different handling.
Are numeric HTML entities supported?
Yes. The decoder supports decimal entities such as © and hexadecimal entities such as 🚀 through the browser HTML parser.
Does this tool execute the HTML I enter?
No. The input is treated as text and is never rendered as active HTML.
