About this tool
Encode text to UTF-8 hex bytes, decode hex back, or switch between text and JavaScript \u unicode escapes.
The BrainCoder UTF-8 & Unicode Converter works with character encodings at the byte level. It converts text to its UTF-8 byte representation, displays Unicode code points, and shows HEX, DEC, and OCT values for each character. This is essential for developers working with internationalization, character encoding issues, or low-level text processing.
UTF-8 is the dominant character encoding on the web, used by over 98% of websites. Understanding how characters map to bytes is critical for debugging encoding errors, building multi-language applications, and working with APIs that require specific character encodings. This tool breaks down any text into its constituent bytes and code points with clear, readable output.
Whether you're troubleshooting a mojibake issue (garbled text from encoding mismatches), verifying how emoji are encoded, or teaching character encoding concepts, this tool provides comprehensive visual output. Everything is processed locally in your browser — no text is ever sent to a server.
