Text to Binary

Turn any text into binary code (space-separated UTF-8 bytes) and translate binary back into readable text. Instant, right in your browser.

πŸ”’ The conversion happens in your browser: nothing is saved or sent anywhere.

How UTF-8 encoding works

Computers store text as sequences of bytes β€” groups of 8 bits (zeros and ones). This converter uses UTF-8, the standard encoding of the web: plain letters, digits and basic punctuation take 1 byte each (an uppercase "H" is 01001000), while accented letters like "Γ©" take 2 bytes β€” 11000011 10101001. Emoji and special symbols can take up to 4 bytes. That is why a word like "cafΓ©" produces more groups than it has letters: it is perfectly normal, not an error.

How to convert binary back to text

Paste the bytes into the binary box, separated by spaces or line breaks: each group must be exactly 8 characters, using only 0 and 1. The tool checks every group and, if something is off β€” a group that is too short, a digit other than 0 or 1, or a byte sequence that does not map to valid UTF-8 characters β€” it tells you exactly where the problem is, without losing what you typed.
