How this works & FAQ
How do I convert text to binary code?
Type or paste a word or sentence into the box above with Encode and Binary selected — each character becomes its 8-bit binary byte, space-separated, instantly.
What's the difference between binary and decimal (ASCII) output?
Binary shows each byte as eight 0s and 1s (e.g. 01001000). Decimal shows the same byte as its ASCII/UTF-8 code number 0-255 (e.g. 72). Switch between them with the format toggle.
Can I convert binary back to text?
Yes — switch to the Decode tab, paste space-separated binary bytes (or decimal codes), and it converts back to plain text.
