problem converting svg to png

[barakganon]

Hello, I am using svg2png to convert this SVG :

<svg width="800" height="600" viewBox="-174 0 820 620" xmlns="http://www.w3.org/2000/svg"> <rect width="300" height="100" style="fill:rgb(0,0,255);stroke-width:3;stroke:rgb(0,0,0);transform: rotate(5deg);"/> </svg>

but the rotation isn't working for me.

Is there a right way to add transform to the SVG that will work correctly?
Thank you
