UTF-8 Encode/Decode

What is UTF-8 Encode/Decode?

UTF-8 is the most widely used character encoding on the web, representing every Unicode character. This tool converts text to UTF-8 byte sequences or restores bytes to readable text — essential for debugging encoding issues in databases and network data.

Key Features

• Multiple formats: hex (e.g. E4 BD A0), percent-encoding (e.g. %E4%BD%A0), binary view.
• Smart decode: auto-detects \x, 0x, %XX and space-separated hex input.
• Emoji support: handles 4-byte Emoji and other multibyte characters.
• Mojibake debugging: analyze byte sequences to find encoding errors.
• Local processing: data never leaves your browser.

How to Use

1. Enter original text or UTF-8 byte sequences.
2. Choose output format and separator.
3. Click "Encode" for byte sequences or "Decode" to restore text.
