UTF-8 Encoder/Decoder

Represent text as UTF-8 hexadecimal bytes or decode hexadecimal bytes back into text.

Use UTF-8 text unless the tool specifically asks for encoded data or a file. Your input stays in this page during the text conversion; some specialized pages load libraries from a CDN.

About UTF-8 Encoder/Decoder

UTF-8 is a common Unicode encoding used for web content and text files. This tool shows the bytes for a string and can decode a valid hex-byte sequence into Unicode text.

How to use UTF-8 Encoder/Decoder

  1. Choose Text to UTF-8 Hex or Hex to Text.
  2. Paste ordinary text or space-separated hexadecimal bytes.
  3. Convert and compare the output with the encoding expected by your application.
Important information: Decoding invalid UTF-8 sequences may fail or show replacement characters. This page focuses on UTF-8 byte sequences, not every character encoding.

Helpful tips

Keep an unchanged copy of important input before making transformations. Test the output in the target application or validator, especially before using generated code, configuration, links, or converted data in production. The tool does not execute the code you paste.
