Encode text to decimal/hex numeric HTML entities (&#NN;) and decode them back. Numeric HTML Entities is a free online tool from the ToolsRift Encoders & Decoders collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Choose Encode or Decode, pick decimal or hex output for encoding, and enter your text. Decoding accepts both &#NN; and &#xNN; forms mixed with plain text.
References like A (decimal) or A (hex) that stand for a character by its Unicode code point, so any character can appear safely in HTML.
To embed characters that would otherwise break markup, or to include symbols and emoji without worrying about file encoding.
Both are equivalent; decimal (😀) is common, hex (😀) matches Unicode's U+ notation. Decoding handles either.
