An ampersand can be represented in HTML three genuinely different but equivalent ways, the named entity &, the decimal reference &, or the hexadecimal reference &, and while a modern browser accepts all three interchangeably, an older parser, a strict XML context, or a system generating markup programmatically often expects one specific format and will choke on or mangle the others. This tool encodes and decodes HTML entities across all three formats, named, decimal, and hexadecimal, converting between them rather than only handling the most common named form.
