UTF-8 Decode

Decode UTF-8 byte sequences into readable Unicode text.

Input Format
Choose hexadecimal or decimal UTF-8 byte values.

How UTF-8 decoding works

UTF-8 stores Unicode characters as one or more bytes. ASCII characters use one byte, while many other characters use multi-byte sequences.

This tool converts the entered byte values into a byte array and decodes that array using strict UTF-8 rules.

Frequently Asked Questions

What input formats are supported?

You can enter UTF-8 bytes as hexadecimal or decimal values.

How should bytes be separated?

Spaces, commas, and line breaks are supported between byte values.

What is a valid byte range?

Each byte must be between 0 and 255.

What happens with invalid UTF-8?

The decoder shows an error and does not replace invalid sequences silently.

Does switching modes keep old output?

No. switchMode(newMode) clears input and output to prevent stale results.

Can I decode emoji and non-English text?

Yes. Any valid UTF-8 byte sequence can be decoded into Unicode text.
