Hi all,
 
here is a Python3 implementation of my file2png program, available

Hope you find it useful, when for example uploading such images to
platforms like X, which does not compress .png images, as I have
tested!

PNG compression is lossless, so it should not matter if the PNG is
compressed, you should get back the same bytes that went in.

Now, if instead you mean "rescale" (reduce/increase size) or other
transformations (RGBI to RGB or RGB to indexed) then those
transformations may alter the content such that you do not get back
what you put in.
