What this tool is good for
This tool converts string and byte data between UTF-8, UTF-16LE, UCS-2, Latin1, Base64, ASCII, Hex, and byte-array forms. It is useful when debugging encoding bugs, inspecting payloads, or preparing data for APIs and protocols.
Encoding notes
- UTF-8 is the most common Unicode encoding used on the web.
- UTF-16LE is the little-endian UTF-16 variant used by this tool, and UCS-2 is treated as its alias.
- Latin1 supports only U+0000 to U+00FF and may truncate higher code points.
- Base64 ignores non-Base64 separator characters such as spaces and line breaks when decoding.
- Hex uses two hexadecimal characters per byte, and incomplete trailing data will be truncated.
- Byte array output represents each byte as a decimal number from 0 to 255 separated by commas.
ASCII note
ASCII only applies to 7-bit ASCII data and is mainly useful for legacy compatibility. In most modern cases, UTF-8 is the better default choice.
