Convert Unicode to Octal

The Convert Unicode to Octal Tool turns any string into its UTF-8 octal byte representation. You just type or paste your text, and it instantly transforms each character including emojis, symbols, and multilingual text into octal format. Every byte is clearly formatted using standard 0o prefixes, making it easy to analyze or use in low-level debugging.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .log, .csv
Total bytes: 0

How to Use:

  1. Paste or type your Unicode text in the left box. It can include emojis, accents, math, or symbols.
  2. The right box instantly fills with UTF-8 octal bytes, each shown like 0o123.
  3. Click “Copy Output” to copy everything.
  4. Use “Export to File” if you want to save it.
  5. Click “Choose File” to import content from a supported .txt, .csv, or .log file.
  6. Need a fresh start? “Clear All” resets everything input, output, file name, and count.

What Convert Unicode to Octal Tool can do:

Convert Unicode to Octal Tool gives you the exact octal bytes used in UTF-8 encoding. That’s super helpful if you’re working with byte-level data, creating encoded payloads, or reverse-engineering file content. It doesn’t just show you raw numbers it breaks everything down into padded 0o values for each byte so there’s no confusion. The whole thing updates in real-time, so it’s perfect for quick experimentation and inspection.

Example:

Input:

🌍

Output:

0o360 0o237 0o214 0o215

Common Use Cases:

Use this tool for encoding study, debugging binary formats, teaching low-level Unicode behavior, or preparing data for systems that support or expect octal byte input. Ideal for hex-to-octal comparisons or embedded development workflows.

Useful Tools & Suggestions:

Breaking characters into octal? Add Line Numbers can help you keep track of each conversion step by step. And if you’re tweaking input first, Trim Whitespace from Text keeps things clean before you start.
