Frequently Asked Questions

How does text to binary conversion work?

Each character is converted to its Unicode code point, then encoded as binary digits. ASCII characters use 8 bits (1 byte), while other Unicode characters may use 16 or 32 bits.

What encoding does this tool use?

The tool uses UTF-8 encoding by default, which is backward-compatible with ASCII and supports all Unicode characters.

Can I convert binary back to text?

Yes. Switch to Binary → Text mode and paste your binary string (space-separated 8-bit groups). The tool will decode it back to readable text.
