Convert Unicode to UTF-8

Whether you’re working with multilingual text or inspecting byte-level encodings, the Convert Unicode to UTF-8 tool helps you see exactly how each character is encoded. Input your Unicode text and get the raw UTF-8 byte output instantly in either decimal or hex, with optional 0x-prefix formatting. It’s clean, fast, and completely offline.

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. Enter any Unicode text into the Input Unicode Text box on the left.
  2. Use the Options box to control formatting:
    • Choose whether output is in hex or decimal.
    • Toggle 0x prefix for hex output.
    • Trim whitespace before encoding if needed.
  3. The UTF-8 Bytes Output will update live on the right.
  4. Click Copy Output to copy the result, or Export to File to save it.
  5. You can also import files in .txt, .csv, .xml, and other safe text formats.

What Convert Unicode to UTF-8 can do:

  • Convert any Unicode string to its corresponding UTF-8 encoded byte values.
  • Show the result in either hexadecimal (e.g., e2 9d a4) or decimal (e.g., 226 157 164) format.
  • Add a 0x prefix to each hex byte if needed.
  • Instantly count total UTF-8 bytes as you type.
  • Load input from common file types and preview it live.

Example:

Input Unicode Text

Hello ♥ Привет 😊

UTF-8 Bytes Output

48 65 6c 6c 6f 20 e2 99 a5 20 d0 9f d1 80 d0 b8 d0 b2 d0 b5 d1 82 20 f0 9f 98 8a

(When using hex output with no prefix.)

Common Use Cases:

This tool is ideal for developers and testers who need to verify UTF-8 byte sequences, debug encoding issues, or analyze character data at the byte level. It’s especially useful when dealing with APIs, databases, or protocols where exact byte representation matters. The live preview and format options make it easy to validate text conversions in real time.

Useful Tools & Suggestions:

After switching to UTF-8, Convert Unicode to Bytes is a good way to see exactly how your data looks at the byte level. And if you’re prepping the text for decoding later, Convert Unicode to Base64 makes it easy to wrap it up safely.
