使用方法

Enter text, then Encode to convert it to HTML entities or Decode to turn entities back into characters. Three encode modes are available: Minimal converts only & < > " and '; Named uses named entities such as © where a name exists and numeric references otherwise; Numeric converts every non-ASCII character to a decimal reference such as ©.

注意事项

Everything runs in your browser. Decoding supports named entities from this tool's table, decimal references (©) and hexadecimal references (©). Unknown names are left unchanged.
