About Text to Binary Converter
Binary representation of text is a fundamental concept in computer science education and a practical tool for debugging encoding issues. This converter works in two directions. Text to Binary: each character's Unicode code point is converted to an 8-bit binary string using charCodeAt(0).toString(2).padStart(8, '0'), and bytes are joined with spaces — so 'Hi' becomes '01001000 01101001'. Binary to Text: space-separated 8-bit groups are parsed with parseInt(b, 2) and converted back to characters with String.fromCharCode(). If the binary input contains invalid groups, an error message is shown. The two-button toggle (Text → Binary / Binary → Text) switches direction. The output appears in a side-by-side panel with a Copy button. Useful for computer science students learning binary encoding, developers debugging character encoding issues, and anyone who needs to inspect the binary representation of a string.
