Loona Text to Binary Converter - And Back Again
Every letter on a screen is stored as numbers, and every number as binary - just 0s and 1s. Computer-science students meet this on day one. Type text to see its true binary form, or paste binary to decode a message someone sent you.
How to use the Text to Binary
- Type normal text, or paste binary code (groups of 8 bits, spaces optional).
- Click the conversion direction you want.
- Copy the result - binary makes a fun secret-code message for friends and students.
How it works
Computers store text as bytes using the UTF-8 encoding: each character becomes one or more bytes, and each byte is written as exactly 8 binary digits. 'A' is byte 65, written 01000001. English letters take one byte each; Urdu letters take two bytes each, which is why their binary looks longer - the tool handles both correctly in both directions, and validates pasted binary before decoding so a stray digit gives a clear error instead of gibberish.
Worked example
'Hi' becomes '01001000 01101001': H is byte 72 and i is byte 105. Paste that binary into the tool and click Binary → Text, and 'Hi' comes back.
Frequently Asked Questions
Is the binary converter free?
Yes - free, no sign-up, unlimited conversions.
Why is each letter 8 digits?
Text is stored in bytes, and a byte is 8 bits (0s and 1s). Each group of 8 digits is one byte - one simple character.
Does it support Urdu and emojis?
Yes - it uses full UTF-8, so Urdu letters (2 bytes each) and emojis (up to 4 bytes) convert correctly both ways.
Can I paste binary without spaces?
Yes - spaces are ignored; the digits are simply grouped into 8s from the start.
Is my text uploaded?
No - conversion happens 100% in your browser.
