UTF-8 Converter — Text to Hex, Decimal & Escape Bytes, and Back

Cách dùng

1. 1 Pick Text → Bytes (encode) or Bytes → Text (decode).
2. 2 Choose output format on encode — hex, decimal, \xAB, or \u{HEX}.
3. 3 Paste input. Decode auto-detects which format you used.
4. 4 Copy the result.

Vì sao dùng công cụ này

• Four output forms — hex, decimal, C/Python \x escapes, JS \u{} escapes.
• Smart decode — recognises hex/decimal/\x/\u input automatically.
• Surrogate-pair safe — codepoint escapes use full Unicode, not UTF-16 units.
• Pure browser logic, zero dependencies.

Câu hỏi thường gặp

UTF-8 Converter là gì?

A UTF-8 Converter is a tool that converts text into its UTF-8 byte representation and back. It can output bytes as hexadecimal, decimal, \xAB escape sequences, or \u{HEX} code-point escapes, and decode those formats back into readable text. The conversions run entirely client-side in the browser, so the input text is never sent to a server.
