Text to Binary Converter
Type text to see its binary representation (each character as an 8-bit byte), or paste binary to decode it back into readable text.
Cómo usarlo
In text-to-binary mode, each character is encoded as its UTF-8 byte(s) written in 8 bits, separated by spaces. In binary-to-text mode, paste groups of 0s and 1s (spaces between bytes) to decode them back.
Useful for learning how computers represent text, for puzzles and CTF challenges, or just for the novelty of writing a message in binary — with a copy button to share the result.
Preguntas frecuentes
How is text converted to binary?
Each character is turned into its numeric byte value (UTF-8), which is then written in base 2 as 8 bits. For example, "A" is byte 65, which is 01000001 in binary.
Why are some characters more than 8 bits?
Letters and symbols outside basic ASCII (accents, emoji, Cyrillic) take more than one byte in UTF-8, so they appear as multiple 8-bit groups. Plain English letters and digits are always a single byte.
What format should binary input be in?
Groups of 0s and 1s separated by spaces, ideally 8 bits per group (a byte). The decoder reads each group as one byte and reconstructs the original text.
Is my text sent anywhere?
No — the conversion runs entirely in your browser using standard text encoding APIs. Nothing is transmitted.
