🔢 Understanding Binary
Binary is a base-2 number system using only 0s and 1s. Basic English letters take 8 bits (1 byte) each. This converter uses UTF-8, so accented letters take 2 bytes and emoji take 4 – and they convert back correctly.

💡 Conversion Formats
- Binary: 8-bit representation (e.g., 01001000 for 'H')
- Hexadecimal: Base-16 representation (e.g., 48 for 'H')
- Decimal: Base-10 ASCII codes (e.g., 72 for 'H')
- Text: Human-readable characters
Tip: Binary output includes spaces between bytes for readability. Hexadecimal and decimal outputs show space-separated values.
📝 Format Examples

- Hex input: Separate values with spaces (48 69 21)
- Decimal input: Separate ASCII codes with spaces (72 105 33)
- Text input: Type normally, all printable characters supported
Frequently asked questions
How do I convert text to binary?
Choose Text as the input and Binary as the output, paste your text and press Convert. Letters such as ü are stored as UTF-8 bytes and convert back correctly.
Does binary input need spaces?
No. You can paste groups separated by spaces or one long run of bits, which is read 8 bits at a time.
