What is UTF8 Decode?

UTF8 Decode converts byte sequences such as E2 82 AC, 226 130 172, %E2%82%AC, or \xE2\x82\xAC into Unicode text. It uses a strict UTF-8 decoder so malformed byte sequences are reported instead of silently replaced.

How to Use UTF8 Decode

1

Paste UTF-8 bytes in hex, decimal, percent, or escaped form.

2

Choose a format or leave auto detect enabled.

3

Copy the decoded text.

Common Use Cases

  • Debugging raw HTTP payload bytes.
  • Decoding percent-encoded UTF-8 snippets.
  • Checking protocol test vectors.
  • Inspecting binary-to-text examples.

Example Input and Output
