Computers store text as sequences of bytes, each representable as 8 binary digits. Seeing text in its raw binary form is a common exercise for learning how computers represent data at the lowest level.
This tool converts text to its binary byte representation, or decodes binary back into readable text.
How it works
Enter text or binary and choose the direction. For text-to-binary, each character's byte value is converted to an 8-digit binary group, space-separated. For binary-to-text, the tool parses each 8-bit group back into its character.
- Enter text or binary.
- Enter direction.

Examples
Converting a short word
"Hi" converts to "01001000 01101001" — the binary byte values for H and i.
Who should use it
- Learning how computers represent text as binary data.
- Encoding or decoding simple binary-represented messages.
Industry applications
- Computer science education
- Software development
Advantages
- Correctly handles multi-byte UTF-8 characters at the byte level.
- Simple, instant conversion in both directions.
Limitations
- Multi-byte characters produce multiple 8-bit groups, which can be unintuitive if you're expecting one group per visible character.
Common mistakes to avoid
- Assuming each visible character always maps to exactly one 8-bit group, when multi-byte UTF-8 characters produce more than one.
- Confusing this character-level binary conversion with numeric base conversion (decimal to binary for a single number).
Best practices
- Use the Number Base Converter instead if you need to convert a single numeric value between bases, rather than encoding text character by character.
Tips
- If you're working with accented characters or emoji, expect more than one 8-bit group per visible character, since those are typically stored as multiple bytes in UTF-8.
