Frequently asked questions
What is binary?
Binary is a base-2 number system using only 0 and 1. Computers store all data as binary - each character is represented as 8 bits (one byte). For example, the letter H is 01001000 in binary.
Why are there spaces between groups?
Each group of 8 bits represents one byte (one character). Spaces separate the bytes for readability. When decoding, spaces are ignored - only 0s and 1s matter.
Is my data sent to a server?
No. All conversion happens in your browser. Nothing is transmitted anywhere.
