Frequently asked questions
 
 
How is text converted to binary?
 
Each character is first converted to its UTF-8 byte value(s), then each byte is represented as an 8-bit binary number. For example, the letter "A" has UTF-8 value 65, which is 01000001 in binary.
 
 
What is the binary representation of a space?
 
A space character (ASCII 32) in binary is 00100000.
 
 
Does this tool support Unicode and emoji?
 
Yes. The converter uses the TextEncoder API which encodes characters as UTF-8. Multi-byte characters like emoji will produce multiple bytes in the output.
 
 
How do I convert binary back to text?
 
Switch to the Binary → Text tab. Paste space-separated 8-bit binary groups (e.g. 01001000 01101001) and the text output will appear immediately.
