About Unicode Decoder

The Unicode Decoder converts \u escape sequences back into the characters they represent, turning an escaped string from code or JSON into readable text with its accents, symbols, and emoji intact. It's the counterpart to escaping and is handy for reading logged or serialized data. Decoding runs locally in your browser with nothing uploaded. To encode in the other direction use the Unicode Encoder, and unescape JSON strings with the JSON Unescape tool.

How to Use

1Open Unicode Decoder and paste or type your data into the input area.
2Adjust any available options to match the result you want.
3Your output is generated instantly — no button-clicking required for most tools.
4Use the Copy or Download button to save your result.

Common Use Cases

Encoding data for URLs, APIs, and data URIs
Debugging tokens, headers, and encoded payloads
Converting between text, hex, binary, and Base64
Safely embedding special characters in code and markup

Frequently Asked Questions

What input does it accept?

It accepts text containing \u followed by four hex digits per character, the standard escape used in JSON, JavaScript, Java, and many other languages, and converts each back to its character.

Is this the same as URL decoding?

No. Unicode decoding reverses \u escapes, while URL decoding reverses percent-encoding like %20. Use the URL Decoder for percent-encoded strings.

Is Unicode Decoder free to use?

Yes. Unicode Decoder is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use Unicode Decoder?

Absolutely. Unicode Decoder runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
