Running on MacOS. I ran the command as you posted and saw a drastic decrease in file size (~3 times if I remember correctly), but the whitespace was still there. I didn't dig into it (and I'm not versed in PNG format), but I can't imagine any way to see such a change in file size without stripping the color depth (although I couldn't tell visually). Perhaps the issue resulted from my image not having a high-contrast border? It was white to light grey.

How to make the background of an image transparent in MS Paint • On your Windows desktop, click the “Start” button then go to “All Programs”. Find the folder for “Accessories” then find and click “Paint”. This will launch your MS Paint interface. • Once you’re on MS Paint, open the photo or image that you want to crop and place on top of another image. • On the toolbar, go to the “Image” tab then click the small arrow right below “Select”.

Make sure to exclude all of the elements and colors that you do not want to see. When tracing, just left-click and hold your mouse. Do not release until you’re done.
