About this tool
Encode each UTF-8 byte of your text as 8 bits, or decode a binary string back to text. Useful for teaching, low-level debugging, and obfuscation puzzles.
FAQs
How are characters represented?
Each byte of the UTF-8 encoding becomes 8 bits, separated by spaces by default.
Will multi-byte characters work?
Yes - 'é' becomes two 8-bit groups (11000011 10101001).
Can I decode binary without spaces?
Yes - spaces are optional; the decoder splits the input into 8-bit chunks.
