Text to Binary Converter
Convert text to binary code and binary back to text. ASCII and UTF-8 encoding with customizable delimiters. Free online binary translator.
About this tool
This tool converts text to binary representation and back. Each character is converted to its ASCII code and then represented as an 8-bit binary number. For example, the letter "A" (ASCII 65) becomes 01000001.
All conversion happens in your browser. No data is sent to any server.

Binary uses only 0 and 1. Each character needs 8 bits (1 byte). The space delimiter makes it easier to read individual characters.
Frequently Asked Questions
How does text to binary conversion work?
Each character is converted to its ASCII code number, then that number is represented in binary (base 2). For example, 'A' is ASCII 65, which is 01000001 in binary.
What delimiters can I use?
You can separate binary groups with spaces (default), no separator, or commas. Spaces make the output most readable.
Does it support Unicode?
The tool uses UTF-8 encoding, so basic ASCII characters use 8 bits and extended characters use multiple bytes.
