Text to Binary Converter
Paste any text and get its binary code, one 8-bit byte per character. This is the encode-only view for when you specifically want text turned into ones and zeros.

How the Text to Binary works
Each character is looked up in ASCII to get a number, then that number is written in base 2 and padded to 8 digits. Spaces separate the bytes so the result stays readable.
Because it is a direct one-to-one mapping, the same input always produces the same binary. Nothing is random and nothing is lost.

Every letter at a glance. Use it to read or write by hand.
History and origins
Binary text encoding is a side effect of how computers were designed to store characters. When you save a document, each letter is already sitting in memory as a byte of eight bits.
The ASCII standard from 1963 fixed which number belongs to which character, so text to binary produces the same result on any modern machine.
Frequently asked questions
Why is every group 8 digits long?
Standard ASCII characters fit in a single byte, which is 8 bits. Padding every value to 8 digits keeps the output aligned and makes it easy to decode later.
Can I convert the binary back to text?
Yes. Use the binary to text tool, or the two-way binary translator, and paste the same space-separated groups to read the message.
