Convert text to binary and binary to text.
Our free text to binary converter makes it easy to translate any text into binary code — and convert binary back to readable text in seconds. Whether you're a student learning computer science fundamentals, a developer debugging encoding issues, or just curious how computers represent characters, this tool handles both directions instantly. Paste your input, choose a conversion mode, and copy the result with one click.
Each character in your text is converted to its Unicode code point, then represented as an 8-bit binary number (padded with leading zeros if needed). For example, the letter 'A' has a code point of 65, which becomes 01000001 in binary. Multiple characters are separated by spaces in the output.
Yes. Paste your space-separated binary groups into the input field and click 'Binary → Text'. Each 8-bit group is parsed as a base-2 integer and converted back to its corresponding character using String.fromCharCode.
The tool validates every binary group and will show an error message if it finds characters other than 0s and 1s. This prevents silent incorrect output. Fix the highlighted group and try again.
Basic ASCII characters (letters, numbers, punctuation) are fully supported. Characters outside the 0–255 range — such as accented letters or emoji — may produce multi-byte code points that exceed 8 bits, so results for those characters may not round-trip cleanly with strict 8-bit binary decoding.
