Escape / unescape

Escape or unescape strings for HTML, XML, JavaScript and JSON — handles entities, unicode escapes and special characters.

Features

Escapes and unescapes for HTML, XML, JavaScript and JSON, including named entities and \uXXXX unicode sequences.
Two-way conversion: encode special characters for safe embedding, or decode them back to readable text.
Processes your strings entirely in the browser — safe for API keys, tokens or any sensitive payload.

How it works

Paste the string you need to escape or unescape into the box above.
Pick the target syntax — HTML, XML, JavaScript or JSON — and whether to escape or unescape.
The result updates live with special characters, entities and unicode escapes handled; copy or download it.

Your files never leave this page

Every conversion runs entirely in your browser using WebAssembly. There is no upload, no server-side processing, no analytics, and no cookies. Open DevTools → Network during the operation and you will see zero outbound traffic.
