Supported byte formats
- Binary bytes such as 01001000
- Hex bytes such as 48 65 6c 6c 6f
- Decimal bytes such as 72 101 108 108 111
How to use Binary Converter
The binary converter turns UTF-8 text into binary, hex, and decimal byte groups, and can decode those byte groups back into text.

Input
HelloOutput
01001000 01100101 01101100 01101100 01101111The converter uses UTF-8 bytes, so non-English characters may use multiple bytes.
Steps
- 1Enter text to generate byte formats.
- 2Copy binary, hex, or decimal bytes.
- 3Paste byte groups into the decoder when you need readable text again.
Common use cases
- Inspect UTF-8 bytes for a string.
- Decode binary examples from docs.
- Compare binary, hex, and decimal byte representations.
Practical tips
- Non-English characters may use more than one UTF-8 byte.
- Binary input expects 8-bit groups such as 01001000.
- Hex input expects two-character byte groups such as 48 65.
FAQ
Is binary the same as Base64?
No. Binary shows raw byte bits, while Base64 is a text encoding for binary data.
Why does one character become multiple bytes?
UTF-8 uses multiple bytes for many non-ASCII characters.
