How it works

3 steps, no account. It runs in your browser and nothing is uploaded.

  1. Enter text or a file

    Type or paste anything, or drop a file onto the input; the Binary updates with every keystroke.

  2. Choose the form

    Spaced or joined: pick in the bar and the result is rewritten in place.

  3. Copy, download or swap

    Copy the Binary, download it as a text file, or press Swap to decode it back.

Where Binary is used

Every bit written out: eight digits per byte, for seeing and teaching. Where Binary does its work.

  • Teaching ASCII

    A is 01000001, a is 01100001: one bit apart. The clearest way to show what a character is to a machine.

  • Bit fields and flags

    A permissions byte, a TCP flags field or a status register reads as bits, each with a meaning.

  • Networking

    An IPv4 netmask, 255.255.255.0, is 24 ones and 8 zeros; subnetting is counted in bits.

  • UTF-8 structure

    A UTF-8 multi-byte character shows its lead and continuation bytes, 110xxxxx 10xxxxxx, once written out.

  • Arithmetic

    Two's complement, overflow and shifts make sense when the bits are in front of you.

  • Puzzles

    A puzzle, a T-shirt, a 'there are 10 kinds of people' joke: binary is also a form of play.
