Using This Tool: Guide & Notes Show guide

The binary translator converts readable text into 8-bit binary byte groups and decodes binary byte streams back into UTF-8 or ASCII text.

How to use it

  • Choose Text to Binary to encode readable text, or Binary to Text to decode complete 8-bit byte groups.
  • Select UTF-8 for ordinary text, symbols, and emoji, or ASCII when you specifically want 7-bit text only.
  • Use the separator and wrapping options to make encoded binary easier to read or copy.
  • Check the byte visualiser and character breakdown to see decimal, hexadecimal, binary, and code point values.

Options and settings

  • Pad every byte to 8 bits keeps byte boundaries visible and is the safest default.
  • Add 0b prefix writes binary bytes in a programming-style format such as 0b01001000.
  • Wrap bytes into rows only changes display formatting; it does not change the underlying bytes.
  • Allow spaces and punctuation lets the decoder accept grouped binary with spaces, commas, pipes, colons, hyphens, and line breaks.
  • Reject invalid UTF-8 makes the decoder fail on malformed byte sequences instead of replacing them with the Unicode replacement character.

Notes

  • Binary translation is encoding, not encryption. It does not make a message private.
  • Binary input must contain complete 8-bit bytes to decode cleanly.

A note from the team

We build these tools because we love cryptography, encoding, and making difficult ideas easier to explore. If they've helped you, even a small coffee means the world to the project. Thank you!
