Text to Binary Converter
Encode text as 8-bit binary, or decode binary back into readable text — both directions, live as you type.
Text to Binary Converter
Each character becomes 8 bits, space-separated. Decoding accepts bytes separated by spaces.

How it works
Computers store text as numbers, and those numbers are ultimately strings of bits. This converter shows that hidden layer: it turns each character into its 8-bit binary code and, going the other way, rebuilds text from binary. The letter H, for example, is 72, which is 01001000 in binary.
Type in the Text box and the binary appears below, one space-separated byte per character; type or paste binary in the Binary box and the readable text appears above. The two boxes are linked, so there is no button to press. Grouping bytes with spaces keeps long strings readable and lets you paste binary from other sources cleanly.
Decoding is validated: each group must contain only 0s and 1s and be a whole number of 8-bit bytes, so a stray digit or a short group shows an error instead of scrambled text. Standard ASCII text round-trips perfectly. Characters above the basic range are encoded from their code unit, so the tool stays focused on ASCII while still handling common input gracefully.
