Can I send non-transparent PNG to adobe stock as a contributor?
I don't see the reason why I should have to convert to JPG and lose quality, as JPG is always lossy compression even in the highest quality.

I would say no. It's not explicitly forbidden, but it makes no sense. JPEG is not that lossy if it is the first generation.

The reason to convert to JPEG is file size.

The guidelines state that png files have transparent backgrounds. If not, send jpeg.
