File2PNG

This is a shell script that stores any file as PNG image. It's based on convert util from Imagemagick.

Usage

Store input_file as output_file.png:

file2png -store input_file output_file.png

Print stored file info (size in bytes, original file name and sha256):

file2png -info container.png

Restore file:

file2png -restore input_file.png output_file

This restores file from input_file.png to output_file.

file2png -restore input_file.png

Ommiting output file name will restore to original file name.

Using - as filename will use stdin/stdout (not supported when using -store).

Example container-image:

Resulting image file size remains almost same.
