What HTML unescape does
HTML unescape reverses entity encoding: sequences like &, <, ', and 👋 become their real characters. When you unescape html online, you translate transport-safe markup back into what an editor would show.
This is not URL decoding, Base64 decoding, or JWT parsing — each layer has its own alphabet. Use this page when the input is clearly HTML entity syntax starting with &.
The tool uses the same browser-native approach as unescape html javascript snippets you see in Stack Overflow: assign to a textarea's innerHTML and read .value. Named and numeric decimal and hex forms are supported per DOM rules.
Malformed sequences — incomplete &# references or stray ampersands — surface as errors or partial output rather than silent corruption.
