Frequently Asked Questions
How does text become binary?
Each character is stored as a number (its UTF-8 code), written in base-2. 'H' is 72 in decimal → 01001000 in binary.
Why 8 bits per character?
A byte (8 bits) is the standard unit — enough for 256 values, covering basic Latin, digits, and symbols. UTF-8 uses 1–4 bytes per character.
Can it decode binary with spaces?
Yes — spaces between byte groups are ignored during decoding.
What about emoji?
Emoji encode as multi-byte UTF-8 sequences; this tool handles them correctly where naive converters break.
Is it free?
Yes — free forever, no signup.
