Binary Converter | How to use and interpret results
View a string as binary UTF-8 bytes rather than as one large binary integer. A Korean syllable occupies several byte groups, which makes the distinction visible.

How to use this tool
For text-to-binary, paste the original string. For the reverse direction, separate groups of zeros and ones with spaces and keep each group within eight bits.
Results and examples
The letter A becomes 01000001, and that byte decodes to A. A multi-byte Korean character requires every UTF-8 byte in its original order to reconstruct the text.
Worked example
The letter A becomes 01000001, and that byte decodes to A. A multi-byte Korean character requires every UTF-8 byte in its original order to reconstruct the text.
Limitations
- Bytes from a different character encoding may not recover their original text.
- Malformed UTF-8 sequences can appear as replacement characters.

Frequently asked questions
How is the letter A represented?
The letter A becomes 01000001, and that byte decodes to A. A multi-byte Korean character requires every UTF-8 byte in its original order to reconstruct the text.
Why can binary input produce replacement characters?
Bytes from a different character encoding may not recover their original text. Malformed UTF-8 sequences can appear as replacement characters.
