How to use the Binary Translator

Type text to convert to binary, or paste binary (0s and 1s) to decode to text. Pick a separator — spaces between bytes is the most readable; no separator is most compact. The tool uses UTF-8 encoding so emoji and accented characters work correctly.

Pourquoi cet outil est important

Binary is the foundation of all digital information — every text character, image, and audio sample is ultimately just 0s and 1s. Teaching the binary representation of text is a classroom staple, and binary-encoded messages remain a popular escape-room and puzzle convention. UTF-8 encoding (variable-length, 1-4 bytes per character) handles Unicode correctly.

ASCII vs. UTF-8 binary

ASCII characters (basic Latin A-Z, a-z, 0-9) are always one byte (8 bits) in UTF-8. Accented characters (é, ñ, ü) are usually two bytes. Most emoji and CJK characters are three or four bytes. Our tool handles all of these correctly — paste a heart emoji and watch the binary expand to 32 bits.

Foire aux questions

How is an emoji 32 bits?
Modern emoji are usually 4 bytes in UTF-8 (32 bits). The first emoji codepoints were 3 bytes, but newer ones (especially skin-tone modifiers) use the higher Unicode plane that requires 4 bytes.

Why doesn\u2019t 7-bit ASCII work?
We default to UTF-8 (8 bits per byte) for compatibility with all modern text. Strict 7-bit ASCII only handles English letters and basic punctuation — anything outside that requires 8-bit or wider encoding.

How do I read binary by hand?
Each byte is 8 bits read left to right. The leftmost bit is 128, then 64, 32, 16, 8, 4, 2, 1. Sum up the positions where there\u2019s a 1. That gives the byte\u2019s numeric value — look up in an ASCII table for the character.

Can I encode files in binary?
Yes mechanically — every file is already binary. But running the binary of a large file through our tool would generate millions of digits. Use a hex dump or binary editor instead.
