What is binary?
Binary is the base-2 numeral system — everything in a computer is ultimately 1s and 0s. This viewer shows you the binary representation of text (as UTF-8 bytes) or numbers (as their base-2 form) and can convert binary sequences back. Group output in 8-bit bytes for readability or see a raw stream.
Key features
- Text → binary (UTF-8 byte representation)
- Numbers → binary (decimal, hex, or octal input)
- Decode binary back to text or numbers
- 100% client-side — nothing is uploaded
Frequently asked questions
What's the difference between text and number mode?
Text mode shows each character's UTF-8 bytes in binary. Number mode converts the numeric value itself to base-2.
Why group in 8-bit bytes?
Computers organize bits into 8-bit bytes; grouping this way makes the output readable and matches how data is stored.
Is my data sent anywhere?
No. Conversion runs entirely in your browser.
