About the Binary Translator
Type any text and see it expressed as binary — each character encoded in UTF-8 and shown as neat 8-bit groups of ones and zeros — or paste a string of binary and turn it back into readable text. Translation happens instantly in both directions, making it effortless to encode a secret message, decode one you've been handed, or double-check homework about how computers really store characters.
Because the converter speaks UTF-8, it handles far more than plain English: accented letters, Cyrillic, Chinese characters and emoji all convert correctly, with multi-byte characters shown as consecutive octets. The decoder is deliberately relaxed about formatting, accepting binary with spaces, line breaks or no separators at all, as long as the digits add up to complete bytes. Everything is computed locally in your browser, so nothing you convert is transmitted anywhere.

Frequently asked questions
How does text become binary?
Each character is encoded into one or more bytes using UTF-8, and each byte is written out as eight binary digits. The letter A is code point 65, which is 01000001 in binary. Multi-byte characters such as é or emoji simply produce two, three or four consecutive octets.
Why do some characters produce more than 8 bits?
UTF-8 is a variable-width encoding: ASCII characters fit in a single byte, but accented letters take two, most Asian scripts three, and emoji four. That's not an error — it's exactly how the text is stored in files and transmitted across the internet, byte for byte.
My binary won't decode — what's wrong?
Check three things: every group must contain only 0s and 1s, the total digit count must be a multiple of eight, and the bytes must form valid UTF-8 sequences. Stray characters like commas, or one missing digit somewhere, are the usual culprits. Spacing doesn't matter — the decoder ignores it.
Do I need spaces between each byte?
No. The decoder strips all whitespace first and then reads the digits in groups of eight, so 0100100001101001 decodes exactly like 01001000 01101001 — both say 'Hi'. Spaces and line breaks are purely cosmetic: use them if they help you read the binary, skip them if not.
Is binary the same as Base64 or hexadecimal?
They're related but different. Binary here means the raw bits written out as 0s and 1s — verbose but fundamental. Hexadecimal packs four bits into each character and Base64 six, so both are compact representations of the same underlying bytes. This tool shows the bits themselves, which is ideal for learning.
