About Text ↔ Binary / Octal / Hex Converter
The Text to Binary, Octal, and Hex Converter translates text between readable characters and numeric bases. Type or paste text to see its binary, octal, and hexadecimal forms, or paste digits in one of those bases to convert them back to text. Encoding uses UTF-8, so accented letters, symbols, and emoji are handled correctly.
The conversion happens entirely in your browser, so the text you enter never leaves your device. It is useful for inspecting how a string is represented at the byte level, preparing data for low-level debugging, or learning how character encoding works.
Frequently asked questions
- Why is the result UTF-8 safe?
- Each character is encoded as its UTF-8 bytes, so multi-byte characters such as emoji convert without corruption.
- How should I format binary input for decoding?
- Separate each eight-bit group with a space so the tool can read the bytes correctly.
- Can it convert between bases without text?
- It converts text to and from each base; for pure number base conversion, decode to text first or use a base converter.
