What is UTF-8?

UTF-8 is the dominant character encoding of the web. It stores every Unicode code point as one to four bytes, is backward-compatible with ASCII, and is self-synchronising. “A” is one byte (0x41), “é” is two bytes (0xC3 0xA9), and “😀” is four bytes (0xF0 0x9F 0x98 0x80). The Convert UTF8 to UTF16 works directly with these UTF-8 byte sequences so every script and emoji is handled correctly.

How it works

The Convert UTF8 to UTF16 runs entirely in your browser using the same Unicode APIs modern browsers use internally. There is no server round-trip: you enter text, the transformation happens locally on your device, and the result appears instantly. Because it is client-side, your data stays completely private.

  2. Enter your input — type or paste your Unicode text, or set the options.
  3. See the live result — output updates as you type.
  4. Copy, download or share the result with one tap.
