Does my binary need spaces between bytes?

Not necessarily. You can paste space-separated bytes, or one continuous bit stream whose length is a multiple of 8 — both are split into bytes automatically.

What if the binary is not valid text?

The tool checks that each group is 8 binary digits and that the bytes form valid UTF-8. If they do not, it shows a clear error instead of garbled output.

Is my data uploaded anywhere?

No. Decoding runs entirely in your browser with JavaScript, so the binary you paste never leaves your device.

Binary to Text Converter

Decode binary back into readable UTF-8 text.

Binary to text converter

Decode binary back into readable text. Paste space-separated bytes or one continuous stream of bits (a multiple of 8 long), and each byte is decoded as UTF-8 to recover the original characters.

Invalid groups or byte sequences are flagged with a clear message rather than producing garbled output. Everything runs in your browser — nothing you paste is uploaded.
