Frequently Asked Questions
How do I convert text to binary?
Enter your text in the input field, select "Text → Binary" mode, and click Convert. Each character is converted to its 8-bit binary ASCII representation.
What is 4-bit vs 8-bit grouping?
Bit grouping adds spaces between groups of bits for readability. 4-bit grouping separates every 4 digits (nibbles), while 8-bit grouping separates every 8 digits (bytes).
Can I convert hexadecimal to binary?
Yes. Select "Hex → Binary" mode, enter a hexadecimal value (e.g. 1A3F), and click Convert. Each hex digit maps to exactly 4 binary digits.
How do I convert binary back to text?
