Has it been ever discussed or explained why C2 does not use TinyPNG or (https://pngquant.org/)?

I make all of my pngs smaller but, according to what I've heard from @Ashley all images are converted to bitmap at runtime, regardless of their format.

Just search - this has been discussed 'ad nauseum'.
If your vision so exceeds your ability, then look to something closer.

TinyPNG is lossy. We won't enable something like that by default, because it degrades the quality of your artwork.

If you opt-in to PNG-8 format via the Image Format dialog in the image editor, C2 will apply similar tools to bring similar file size savings.

But if we use Tiny PNG, that would still decrease the size of our game. Right?

@Usman Haq from what I understand: yes, but it decreases the quality and may sometimes be visible without zooming in.
So I think this you can experiment and see if you are satisfied?

You could also replace all your artwork with solid black rectangles. That would really decrease the size of your game because that kind of image compresses incredibly well. It would however have quite an adverse effect on the quality of your artwork. So there is a tradeoff to be made 8-)
