Text to Binary Converter

How text becomes binary

Computers store text as numbers. Each character is first mapped to a Unicode code point, then encoded as bytes with UTF-8, and each byte is written as eight bits (0 or 1). Plain English letters take one byte each — “A” is 65, which is 01000001. Accented letters take two bytes, and most emoji take four: “😀” is 11110000 10011111 10011000 10000000.

Binary, hex, octal and decimal

The same bytes can be written in different bases. Hex (base 16) is the compact form developers use — “Hi” is 48 69. Octal (base 8) appears in Unix permissions, and decimal byte values (72 105) are what you see in ASCII tables. Pick a format above; the decoder reads all four.

Decoding binary

Paste groups of 8 bits separated by spaces, commas or new lines — or one long string of bits, which is split into bytes automatically. The tool reports bytes that aren’t valid UTF-8 instead of silently showing garbage, which helps when a puzzle or CTF uses a different encoding.
