How to convert SVG icon to favicon

Use this command to convert a SVG icon with transparent background to an exactly 32x32px (padded) PNG image:

convert -background none "Logo.svg" -resize 32x32 -gravity center -extent 32x32 "Logo.png"

Same for 16x16px:

convert -background none "Logo.svg" -resize 16x16 -gravity center -extent 16x16 "Logo.png"
