How to use it

  1. Paste or type your text, or load the example.
  2. Choose any options, then select Decode binary.
  3. Review the result, then copy it or download a text file.

Accepted binary input

Enter complete groups of eight bits, either joined together or separated by whitespace. Only 0 and 1 are accepted. A separated group may contain several complete bytes. The bytes must form valid UTF-8; arbitrary binary files or older text encodings are not supported.

Pasted line endings are normalized by the browser to LF before encoding. Decoded control characters may be invisible, and the text box may display CR as LF. Copy and download preserve the exact decoded result.
