Binary Translator
Convert text to binary — or binary back to text — as you type. The computer's own alphabet, two symbols only: 0 and 1.
Each character becomes one 8-bit group. In the binary box, keep a space between groups so the decoder can split them correctly.
How Binary Works
Binary is a counting system with only two digits — 0 and 1 — called bits. Computers use it because their circuits understand exactly two states: off and on. Eight bits together make a byte, and one byte is enough to store a single character of text.
Text becomes binary through a code table called ASCII: every character owns a number, and that number is written in binary. Capital A is 65, which is 01000001. The letter H is 72 → 01001000, and i is 105 → 01101001 — so "Hi" in binary is 01001000 01101001. Try it in the tool above.
Binary and Morse: Cousins
Binary and Morse code are built on the same idea — a whole language squeezed into two symbols. Morse uses a short signal and a long one (dot and dash, 1840s telegraph); binary uses 0 and 1 (modern computing). Morse came first by about a century, which makes it the original two-symbol code. Many Morse fans learn binary next, and the other way round — if that is you, our Morse alphabet chart is the place to start.
Frequently Asked Questions
How do I convert text to binary?
Type in the Text box. Every character is converted to its 8-bit binary form as you type.
How do I read binary back as text?
Paste the 0s and 1s into the Binary box, with a space between each 8-bit group. The text appears above instantly.
Why 8 bits per character?
Text is stored using ASCII/UTF-8, where the basic characters each fit in one byte — 8 bits. 256 possible values (0–255) are more than enough for letters, digits and punctuation.
