*** Clarification about "Transparent PNG" pictures ***
This image format is mostly used for web pages. It's less supported on operating systems (such as iOS) and most photography apps.
However, these images are fine when used in web-sites / inside some apps [!for!] / desktop photo editor softwares / or submitting avatar pictures on web.
The iOS Photos app displays the transparent pixels as white / and sometimes with sudden color-change to black. For most pictures, the transparency would be visible when you are playing (finger-zooming) with a thumbnail in photo gallery.
Another way to find transparency is to open the picture in "Circle Crop app" and then zoom-out with two fingers to view any transparent area.
