Frequently asked questions
What encoding is used?
Standard 8-bit ASCII encoding, where each character becomes an 8-bit binary number (e.g., "A" = 01000001).
Can I convert binary back to text?
Yes! Switch to "Encoded → Text" mode and paste your binary string with spaces between each 8-bit group.
What is the difference between binary and hex encoding?
Binary uses 8 digits per character (0s and 1s). Hex is more compact — 2 digits per character using 0–9 and A–F.
