What does this tool do?
Binary Hex converts space-separated bytes in both directions: turn binary bytes into hexadecimal or hex bytes back into binary, while also showing the octal and decimal equivalents at the same time. It's practical for developers and networking or embedded-systems students.
How to use it
- Enter the text you want to encode or decode.
- The conversion happens automatically.
- Copy the result and use it safely.
Two-way byte conversion
In Binary → Hex mode, type space-separated 8-bit bytes like '01001000 01100101' and each byte becomes a two-digit hex value (48 65). In Hex → Binary mode, enter hex bytes such as '48 65 6C' to get their 8-bit binary form. Whichever mode you choose, the tool also lists octal and decimal values, so you can compare all four representations at a glance.
Flexible input and cleanup
Input is filtered automatically: in binary mode any character other than 0 and 1 is ignored, and in hex mode anything outside 0-9 and A-F is dropped. Bytes are split on whitespace, so even messy copy-pasted data is usually parsed correctly. A copy button beside each output line puts the result on your clipboard in one click, and an invalid byte triggers a clear error message.
Frequently asked questions
Why must I separate bytes with spaces?
The tool treats each whitespace-separated chunk as a single byte. That way 01001000 and 01100101 map to distinct characters; if you run them together, the result may differ from what you expect.
Can I enter a single hex digit?
Yes, a single digit like '8' is valid and is padded to 8 bits when converted to binary (00001000). For readability, full bytes such as 48 or 65 are still recommended.
How is this different from Binary Converter?
Binary Hex focuses on converting multi-byte sequences between binary and hex; Binary Converter handles the bases of single numbers and text encoding instead.
