About This Tool

The UTF-16 Encoding Converter translates textual data between UTF-16 encodings (BE and LE) and preserves Unicode code points during round-trips. It accepts input as text or as hex bytes and outputs the equivalent content in a chosen UTF-16 format. This is useful for APIs, logs, and data files that require specific endianness or BOM handling. The tool operates on the Unicode representation, ensuring surrogate pairs remain valid when converting between endianness. Conceptually, it decodes source data to code points, then re-encodes to the target UTF-16 form, emitting a BOM if requested or detected. Core strengths include explicit control over endianness, BOM presence, and support for both string and hex representations to aid debugging and verification. It is designed for developers, data engineers, localization QA, and migration specialists who need deterministic, reproducible results across platforms.

How to Use

  1. Provide input data as text or UTF-16 hex bytes.
  2. Select source encoding (UTF-16BE/UTF-16LE) or enable BOM auto-detection.
  3. Choose target encoding and BOM preference.
  4. Run conversion.
  5. Retrieve output as text or hex bytes.

Frequently Asked Questions

Find Quick Answers

What encodings are supported?
The tool supports UTF-16BE and UTF-16LE, with optional BOM handling and auto-detection when a BOM is present. Internal processing uses a Unicode code-point model for accuracy.
How does BOM affect results?
If BOM is auto-detected, the output will reflect the detected endianness. If BOM is requested, it will be emitted in the result; mismatch warnings may be shown for clarity but do not corrupt data.
How are surrogate pairs handled?
Characters outside the Basic Multilingual Plane are encoded as surrogate pairs in UTF-16. The converter validates pairing, and unpaired surrogates trigger explicit errors to prevent data corruption.
Can I process multiple inputs at once?
Batch processing is available in advanced mode, allowing sequential conversion of multiple strings or hex blocks while preserving individual output encodings and BOM options.
