How is text turned into binary?

Each character is converted to its numeric code in UTF-8, and each byte of that code is written as eight binary digits. The capital letter A is 01000001, a space is 00100000, so "Hi" comes out as 01001000 01101001. Accented letters and emoji take several bytes, so their binary is longer, and bytes are separated by spaces to stay readable.

What binary format can I decode?

You can paste binary as space-separated groups, which is the safest format, or as one continuous run of bits whose length is a multiple of eight. The decoder reads each byte, rebuilds the original characters and shows a clear message if a group is not valid binary or does not form valid text.

Why are spaces between bytes helpful?

Splitting binary into eight-digit groups separated by spaces makes it readable and lets the tool decode it without guessing where one byte ends and the next begins. An unbroken string still works as long as its length is a multiple of eight, but spaced bytes are easier to check by eye.

Text to Binary Translator

Translate text to binary and binary back to text, both ways, with each character shown as space-separated 8-bit bytes. Paste text to encode it, or paste binary to decode it. A free text to binary translator that runs in your browser.

Translate text to binary and binary back to text, both directions, with each character shown as a space-separated 8-bit byte. This text to binary translator is useful for learning how computers store letters, for puzzles, and for checking a binary string by decoding it. Paste text to encode it, or paste binary to decode it, and copy the output. Plain letters take one byte each, while emoji and accented characters take several.
