Frequently asked questions
How is text converted to binary?
Each character is encoded as UTF-8 bytes, and every byte is written as an 8-bit group. For example, "H" is byte 72, which is "01001000" in binary — so "Hi" becomes "01001000 01101001".
Does it handle emoji and accented characters?
Yes. The converter is UTF-8 aware: characters like é or 😀 are encoded as multiple bytes (2–4 groups each) and decode back exactly.
How do I convert binary back to text?
Switch to the "Binary → Text" tab and paste 8-bit groups like "01001000 01101001". Spaces, commas, and line breaks between groups are all fine. Invalid sequences show a friendly error.
Is my text uploaded anywhere?
No. Conversion happens entirely in your browser with JavaScript. Nothing you type ever leaves your device.
Why would I need binary?
It's great for learning how computers store text, debugging encodings, CTF puzzles, and low-level programming.
