Binary Translator
Convert text to binary and binary back to text, with full UTF-8 support.
Each character is encoded as its UTF-8 bytes in 8-bit binary, so emoji and accented letters round-trip correctly. Decoding ignores any spaces or line breaks between the groups. Runs entirely in your browser.

What binary is for
Binary is how computers store every character under the hood. Translating to and from it is useful for learning how encoding works, solving puzzles, or sending a message in a deliberately low-tech way.
Questions
How is text turned into binary?
Each character is encoded as its UTF-8 bytes, and every byte is written as eight 0s and 1s. Plain English letters become one group each; emoji and accented letters span several groups, which is why they round-trip perfectly.
What format does the decoder expect?
Groups of eight 0s and 1s, one per byte. Spaces and line breaks between the groups are ignored, so you can paste binary with or without separators. Input that isn't a whole number of bytes shows a clear error.
