Frequently Asked Questions

What is binary code?

Binary is a base-2 numbering system using only 0 and 1. Computers store all data in binary. Each letter is represented by a unique pattern of 8 bits (1 byte).

Why are there 8 bits per character?

Standard ASCII characters fit in 7 bits, but we use 8-bit encoding (a byte) for consistency and to support extended character sets.

What does 01000001 represent?

01000001 is the binary for decimal 65, which is the ASCII code for the capital letter 'A'.

Can I convert back from binary to text?

Yes! Use our Binary to Text Converter tool to decode binary back to readable text.

Does it support Unicode/emoji?

The tool converts based on character codes. For non-ASCII Unicode characters, the code point may exceed 8 bits and will be shown as their actual code point in binary.
