Character Encoding

Use this converter to inspect how text maps to bytes and Unicode code points. UTF-8 views show the actual bytes commonly used in files, APIs, and network protocols; UTF-16 shows JavaScript code units.

ASCII modes are intentionally strict: non-ASCII characters such as emoji or CJK text will show an error instead of silently replacing data.
