Unicode Escape / Unescape

The Unicode Escape tool converts text into \uXXXX escape sequences - the format used in JSON payloads, Java and JavaScript source, and many other places where non-ASCII characters must be encoded. Astral characters such as emoji are emitted as surrogate pairs and can be decoded back losslessly. A \u{…} and \xXX input style are also accepted when decoding.

The conversion runs entirely in your browser. Your text never leaves the device.
