How to Use Text to Binary Converter

To convert text to binary, type or paste your text into the input field. Each character in your text is converted to its 8-bit binary representation based on the ASCII or UTF-8 character encoding standard. The binary output appears immediately in the output panel.

A reference table below the output shows each character alongside its decimal ASCII value, hexadecimal value, and binary code — useful for learning or verifying the conversion. You can copy the binary output with the Copy button. Spaces between binary groups can be toggled for readability.

Frequently Asked Questions

How is text converted to binary? expand_more

Each character is looked up in the ASCII or UTF-8 encoding table to find its numeric code point, which is then expressed as an 8-bit binary number. For example, the letter 'A' has the code point 65, which is 01000001 in binary.

What encoding does the converter use? expand_more

The converter uses ASCII for standard Latin characters. For Unicode characters outside the basic ASCII range (code points above 127), UTF-8 encoding is applied.

Can I convert spaces and punctuation to binary? expand_more

Yes. All printable ASCII characters, including spaces, punctuation, and numbers, are converted to their correct binary representations.

What is the binary representation of a space character? expand_more

A space character has the ASCII code 32, which is represented as 00100000 in 8-bit binary.

What is the reverse operation? expand_more

To convert binary back to readable text, use the Binary to Text tool. It accepts space-delimited or continuous binary strings and decodes each 8-bit group back to its character.
