HTML Entities is a free encode & crypto tool that runs entirely in your browser — escape & unescape entities. No upload, no account, no limits.
Escape and unescape HTML entities. Encoding converts &, <, >, " and ' into their safe entity forms (with an option to also escape every non-ASCII character); decoding turns entities back into literal characters using the browser's own parser.
The five HTML-significant characters &, <, >, double-quote and single-quote, with an optional pass that also escapes non-ASCII as numeric entities.
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
