You should be aware that any PNG images sent through kindlegen will be converted to either GIF or JPEG.
(Disassemble the azw or mobi and see what the images have become.)

A JPEG might be much larger and/or much blurrier than your PNG.
Best to convert diagrams to GIF yourself and they will stay as-is.

You can make them more compact. I use Irfanview -- first make greyscale if not already. Then look at the colour depth. 2 colours gives you brutal jaggies; 4 colours may be OK with decent resolution, 16 is enough for almost all diagrams unless you have subtle shading, rarely do you need 256 except for photos (and they are better as jpegs).
