A Python package that can be used to transfer files with QR codes. Input a file, get QR code images. Print, email, or otherwise share your codes. Re-input these QR codes, get your original file back.

This package is directly invokable as a module:

$ python3 -m qrcode_file_transfer <args>

In addition, the provided setup.py installs an alias that can be run directly from the command line:

$ qrcode_file_transfer <args>

usage: __main__.py [-h] [--output_dir OUTPUT_DIR]
                   {encode,decode} input_files [input_files ...]

Convert a file to a series of QR images and back again.

positional arguments:
  {encode,decode}       The mode of operation. Encode a file into QR code or
                        decode QR codes into files.
  input_files           The files to encode or the QR codes to decode.

optional arguments:
  -h, --help            show this help message and exit
  --output_dir OUTPUT_DIR
                        The output directory to write files to. Will be
                        created if it doesn't exist. (default: current working
                        dir)

The following command will encode the license and readme files into QR codes and save those images into a directory called out.

qrcode_file_transfer --output_dir=out encode LICENSE README.md

This will take the images generated in the previous command and convert them back into the original files. These files will be placed in the out directory.

qrcode_file_transfer --output_dir=out decode out/*.png

• This is not intended to be used for large files.
• If possible, compress files before encoding into QR codes.
