Is it me or am I the only one who wants my JPG's untouched for my 2D puzzle game? I would just like them to stay the way they are. I use Photoshop to get them just right - the right size, the right color profile, everything right.
Is there a method to slip Unity the skip-me for post-process of the images before compile? And just take them straight?
After you imported your jpg to unity, click on it, and navigate your inspector window to the bottom. You can set the compression property here for every target or to specific build targets.

This way your asset will not be compressed in builds, btw JPG is already compressed.
