About this tool
Converts text to its binary (base-2) representation and back, one byte per group of 8 bits.
When you’d use it
- Learning or teaching how character encoding works at the byte level.
- Checking the raw bit pattern behind a short string for a networking or systems exercise.
Frequently asked questions
- Why is the binary output so much longer than my input?
- Every character becomes a full byte (8 bits), so a 10-character string becomes 80 characters of 1s and 0s, which is expected rather than a bug.
- Does it handle Unicode text?
- Multi-byte UTF-8 characters are encoded as multiple 8-bit groups, so the output reflects the character's true UTF-8 byte count rather than just how many glyphs you typed.
