Frequently Asked Questions
What is binary code?
Binary is a base-2 number system using only 0s and 1s. Computers store all data — text, images, programs — as binary.
How is text converted to binary?
Each character is converted to its ASCII code (a number), and that number is written in binary (base-2). E.g. 'A' = 65 = 01000001.
What is 'Hello' in binary?
01001000 01100101 01101100 01101100 01101111 — each group of 8 bits (1 byte) represents one character.
Is my text sent to a server?
No. All conversion happens entirely in your browser. Your text never leaves your device.
