Binary Translator

Computers store every character as a number, and this tool exposes that mapping. When encoding, it reads each character of your text, takes its code point with JavaScript's charCodeAt, converts that number to base 2, and left-pads it to 8 digits so every character lines up as one byte. The letter 'A' is code point 65, which becomes 01000001; a space is 32, or 00100000. Groups are joined with a single space for readability. Decoding reverses this: the tool splits your input on whitespace, parses each chunk as a base-2 integer, and turns it back into a character with String.fromCharCode. This is a straightforward, naive converter rather than a true UTF-8 byte encoder. It works perfectly for the ASCII range (code points 0–127), which covers English letters, digits, and common punctuation. Characters above 255 — like accented letters or emoji — return UTF-16 code units that exceed 8 bits, so their output is wider than a byte and will not round-trip cleanly through real UTF-8 systems. If you need standards-correct multi-byte encoding, use a dedicated UTF-8 byte-sequence tool instead.
