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).

Also, if using Photoshop, DO NOT use "Save as..." when saving images for ebooks. Use the "Export>Save for Web (legacy)" method instead. This will create more compact files for PNG, JPEG, or GIF than the "Save"/"Save as..." functions. "Save for Web" omits a bunch of Ps specific metadata that is useless except when reopening the file in Ps and otherwise only makes the files larger.
