Binary Encoder/Decoder — Free Online Text to Binary Converter
Convert text to binary representation (8-bit bytes) and decode binary back to text — encodes each character as an 8-bit binary number.

Binary Text Encoding: How Computers Store Characters
At the lowest level, all text on a computer is stored as binary — sequences of 0s and 1s. When you type 'Hello', your computer stores it as five bytes: 01001000 01100101 01101100 01101100 01101111. Binary text encoding makes this underlying representation visible.
This tool uses UTF-8 encoding, the universal standard for text on the web. ASCII characters (U+0000 to U+007F) are 1 byte. Latin-extended and common symbols (U+0080 to U+07FF) are 2 bytes. Most other Unicode characters are 3 bytes. Emoji and rare scripts are 4 bytes. The clever design of UTF-8 ensures ASCII files are automatically valid UTF-8.
Understanding binary encoding helps when studying how text encoding works, debugging encoding bugs (the classic "’" instead of apostrophe is a UTF-8 misread as Latin-1), writing file parsers, understanding how Unicode handles combining characters, or analyzing protocol traffic at the bit level.
