Frequently Asked Questions
- How does text to binary conversion work?
- Each character in text is represented by a numeric code (like ASCII or UTF-8). The converter takes each character, finds its byte value, and converts it to the chosen number system. For example, the letter "A" has a byte value of 65, which is 01000001 in binary, 41 in hex, 101 in octal.
- What is the difference between binary, hex, octal, and decimal?
- These are different number systems (bases). Binary is base-2 (0 and 1), used by computers internally. Hexadecimal is base-16 (0-9 and A-F), commonly used in programming for compact byte representation. Octal is base-8 (0-7), used in Unix file permissions. Decimal is base-10 (0-9), the standard human number system.
- Can I convert binary back to text?
- Yes! Click the swap button (↔) to switch to Binary→Text mode. Paste your binary, hex, octal, or decimal values separated by spaces (or your chosen delimiter) and the tool will convert them back to readable text.
- What is byte padding?
- Byte padding adds leading zeros so all values have the same length. For example, without padding the letter "A" in binary is 1000001, but with padding it becomes 01000001 (8 digits). Padding makes output more readable and consistent.
- What encoding should I use?
- UTF-8 is the default and handles all characters including emojis and international text. ASCII only supports basic English characters (codes 0-127). Use UTF-8 unless you specifically need ASCII-only output.
