Frequently asked questions

5 answers
Each character in the text is converted to its ASCII (or Unicode) code point, then that number is expressed in binary. For example, the letter 'A' has ASCII code 65, which is 01000001 in binary. Spaces between bytes make the output easier to read and copy.

About Text to Binary Conversion

Every character in digital text is ultimately stored as a number, and that number is stored in binary. The ASCII standard assigns a number from 0 to 127 to each common Latin character, control code, and punctuation mark. UTF-8 extends this to cover all Unicode characters using 1 to 4 bytes per character. This converter exposes those underlying binary values — useful for learning about character encoding, debugging low-level data issues, or exploring how text is represented in computer memory.
