What is binary?
Binary is the number system computers use — just two digits, 0 and 1. Every letter, number, and symbol you type is stored as a pattern of 8 binary digits (called bits), known as ASCII code. For example, the letter "A" is 01000001. When you see long strings of 0s and 1s in movies, that's binary!

FAQs
Is this binary translator free?
Yes, completely free with no limits.
What binary format do you use?
Standard 8-bit ASCII — each character becomes 8 binary digits separated by spaces, the most common format.
Can it handle emojis or special characters?
Basic emojis may not translate perfectly since they use more than 8 bits. Letters, numbers, and standard punctuation work perfectly.
Does my text stay private?
Yes. Translation happens entirely in your browser — nothing is sent to our servers.
Does it work on my phone?
Absolutely — the tool works on phones, tablets, and computers.
