Über HTML Entity Encoder/Decoder
Der HTML-Entity-Encoder/Decoder converts special characters like less-than, greater-than, ampersand, and quotes into their named HTML entity equivalents (<, >, &, ", ') or numeric character references and decodes them back to the original characters. Correct HTML entity encoding is the primary defense against Cross-Site Scripting (XSS) when inserting user-controlled content into HTML contexts, and is mandatory for correctly rendering reserved characters without them being interpreted as markup.
So verwenden Sie es
Fügen Sie text containing special characters und klicken Sie auf Encode to convert all HTML-significant characters to their safe entity equivalents — choose between named entities (&) and decimal numeric references (&) depending on your target context. To decode, paste HTML-encoded text und klicken Sie auf Decode to restore the original characters. The tool handles all 253 named HTML5 entities including extended Latin, Greek, mathematical, and typographic characters.
