<, >, &, ", ') in web browsers requires encoding them into standardized HTML character entities (e.g. <, >, &, "). Without proper entity encoding, browsers interpret these symbols as HTML markup, resulting in broken page layouts or severe Cross-Site Scripting (XSS) security vulnerabilities. The HTML Entities Encoder & Decoder provides bidirectional conversion in real time: encode raw text into named or numeric HTML entities, or decode entity strings back into human-readable plain text with one click.HTML entity encoding replaces reserved DOM characters with safe character references:
& (Ampersand) $\rightarrow$ & (or &)< (Less Than) $\rightarrow$ < (or <)> (Greater Than) $\rightarrow$ > (or >)" (Double Quote) $\rightarrow$ " (or ")' (Single Quote / Apostrophe) $\rightarrow$ ' (or ')©, ™, €) use mnemonic names. Numeric entities use decimal (©) or hexadecimal (©) Unicode code points, which are universally supported across XML and legacy parsers.<script>alert('xss')</script> execute malicious code in the victim's browser. Encoding < to < renders the code safely as plain text. and —.&, ©) and Numeric Decimal/Hexadecimal Entities (&, &).<, >, &, ", '.Scenario: Displaying a JavaScript code snippet inside a blog tutorial without executing it.
