Decode HTML entities
Turn HTML entities back into the characters they represent.
What to know
Named entities, decimal references such as A, and hexadecimal references such as B are all decoded. Anything unrecognised is left exactly as written rather than being guessed at or silently dropped.
This uses a lookup table rather than a real HTML parser, so there is no way for the input to be interpreted as markup while decoding.
Questions
Is anything uploaded to a server?
No. Every tool on this site runs inside your browser using standard web APIs. There is no upload, no account, no logging and no server holding your data afterwards. You can confirm it by opening your browser's developer tools and watching the network tab stay empty while you work.
