Text to Binary

Step 1 / 3
Mode
Next

Every character you see on screen is, at the bottom of the stack, a run of ones and zeros. This converter flips between those two representations using 8-bit ASCII: each character becomes one byte (eight binary digits) separated by spaces. It is the format you see in CS101 exercises, capture-the-flag challenges, geocache puzzles and the occasional bot-vs-human gag.

How to encode and decode

  1. 1

    Pick a mode

    Encode to go text -> binary. Decode to go binary -> text.

  2. 2

    Paste your input

    For decoding, separate each byte with a space: `01001000 01101001`.

  3. 3

    Run the conversion

    Each character is mapped to its 8-bit representation, left-padded with zeros.

  4. 4

    Copy the result

    Decoded text is assembled in order; any byte outside 0 - 255 is silently skipped.

newline 10 00001010

A few things worth knowing

  • Standard ASCII only covers 0 - 127. Values 128 - 255 are “extended ASCII” and vary by code page; we treat them as single bytes which is usually what you want for Latin-1 text.
  • Unicode characters beyond U+00FF get encoded as multiple bytes in UTF-8 before the conversion runs, so é becomes two bytes and an emoji can be four.
  • Decoders are picky about spaces. Each group of 8 must be separated from the next. Groups shorter than 8 are treated as invalid and skipped.
  • Leading zeros matter. 1000001 is seven digits and ambiguous; 01000001 is eight and decodes cleanly to A.

Typical uses

  • CS exercises (“write the binary for your first name”).
  • Puzzle hunts and geocaches, where a binary string is the final clue.
  • Sanity-checking a serial protocol or a hex dump by eye.
  • Pranks in a team chat.

Frequently Asked Questions

Emojis and most non-ASCII characters are multi-byte in UTF-8. The converter encodes each underlying byte as 8 bits, so a 4-byte emoji becomes 32 bits of binary.

It is skipped. Decoding only accepts groups of 1s and 0s that represent a single byte.

Same numbers, different base. Binary uses base 2 with 8 digits per byte; hex uses base 16 with 2 digits per byte. A is 01000001 in binary and 41 in hex.

The decoder splits on any whitespace, so spaces, tabs and line breaks all work. Commas must be removed first.
