How text becomes binary
Computers store everything as 0s and 1s. Each character has a numeric code, and that number is written in binary. For example the letter A has the code 65, which is 01000001 in 8-bit binary.
This converter writes each character as an 8-bit group separated by spaces. To decode, paste binary groups separated by spaces and choose Binary to Text.
Quick examples
- A = 01000001
- a = 01100001
- Space = 00100000
- Hi = 01001000 01101001
💡 Tip: When decoding, make sure each group has exactly 8 digits and groups are separated by a space.
Frequently Asked Questions
Does it support all characters?
It works best with standard ASCII characters. Characters above code 255 are not represented in 8 bits.
Why 8 bits per character?
One byte is 8 bits, which covers the standard ASCII and extended character range.
