What this tool does
The text is first encoded as UTF-8, so a multi-byte character such as an emoji or an accented letter produces several three-digit octal byte groups, matching the classic octal dump format used by tools like od.
How to use it
- Type or paste the text you want to encode.
- Read the resulting octal byte groups below.
- Copy the octal bytes for use elsewhere.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Is my text uploaded anywhere?
- No. Encoding happens with JavaScript in your browser tab, so the text never leaves your device.
- Why does one character sometimes produce more than one byte group?
- UTF-8 encodes characters outside the basic ASCII range as two to four bytes, so this tool shows every byte separately, the same way the text is actually stored.
- Why octal instead of hex?
- Octal byte dumps are still common in Unix tooling and older documentation. Use the Text to Hex converter if you need hexadecimal instead.
