Converting files with AI, is it possible?

Question

Python

Recently, I had such a question whether it is possible to convert files using neural networks.
For example:
From JPG to PNG from one text format to another.
But I didn't really look for ways. So if the answer lies on the surface, don't throw tomatoes.
The question is how can this be done?

Answer 1

Why AI for deterministic operations?
The maximum can be pulled by the ears - calculating the compression ratio (loss) for converting raw / tiff to jpg by evaluating the plot and for supposedly nudity, increase accuracy to 100%, and lower it to 50% for drawn comics.
Well, or there, finding the text rather - not to press in jpg, but in djwu for example.
