Convert Unicode to UTF-16

Looking to inspect how your Unicode characters are encoded in UTF-16? The Convert Unicode to UTF-16 tool takes any input string and outputs its byte-level representation in UTF-16 Little Endian encoding. You can format the output as hex or decimal, prefix values with 0x, and see the total number of bytes instantly.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .log, .json, .csv, .tsv, .xml, .md, .ini, .yaml, .yml, .html, .htm, .css
Total bytes: 0
Options
Output as hex
Prefix hex with 0x
Trim input whitespace

How to Use:

  1. Paste your Unicode string into the Input Unicode Text box.
  2. In the Options panel, choose your output format (hex or decimal).
  3. Toggle whether hex bytes include a 0x prefix.
  4. Decide if you want to trim input whitespace.
  5. View the UTF-16 byte output in real-time in the right pane.
  6. Use Copy Output or Export to File when done.

What Convert Unicode to UTF-16 can do:

  • Show the UTF-16LE byte representation of any Unicode string.
  • Display bytes in either hexadecimal or decimal.
  • Add optional prefixes to each byte.
  • Count total bytes for easy reference.
  • Support common file imports and live output preview.

Example:

Common Use Cases:

This is useful for debugging encoding issues, building test cases for UTF-16 input fields, or converting data for binary APIs. If you need to understand how a string is encoded at the byte level in UTF-16LE, this tool gives you full control and transparency with real-time formatting options.

Useful Tools & Suggestions:

If you’re working with UTF-16, Convert Unicode to Hex can help you verify the exact encoding output. And if you’re juggling formats, Convert UTF-8 to Unicode is useful for pulling in text from a different encoding before making the switch.
