Wrong svg conversion?

Question

css

Hello!
My problem is that I can't figure out why converting png to svg results in one white spot. I tried to convert both with the help of Inkscape and with the help of various online converters. But there are only two results:
1. Smeared white .svg
2. Smeared black .svg
I don't think it should look so bad, so I'm asking for help.

Answer 1

png - raster
svg - vector
You hardly know how they differ. so -> google
