What character encoding is used?

The tool uses the character's Unicode code point via JavaScript's charCodeAt(), which gives the correct binary value for standard ASCII characters (0-127). For multi-byte UTF-8 characters, the output reflects the JS internal UTF-16 code unit.

Why are bytes separated by spaces?

Spaces make each 8-bit group visually distinct and easier to read. The binary-to-text converter expects this space-separated format.

What happens with invalid binary input?

If a group contains characters other than 0 and 1, or does not have exactly 8 bits, an inline error is shown and the conversion stops at that point.

Can I convert binary without spaces?

The converter expects space-separated 8-bit groups. You can manually add spaces to a continuous binary string to use this tool.

Summary

Convert ASCII/UTF-8 text to space-separated 8-bit binary groups and back.

How it works

For text-to-binary conversion, each character's Unicode code point is converted to an 8-bit binary string using charCodeAt(). For binary-to-text, each 8-bit group is parsed as an integer and converted back to its character. Bytes are separated by spaces.
