Answer 1

To create an ICO file from a SVG while keeping aspect ratio:

1. look for SVG proportions (eg. 1920x1080)
2. for a max 256px wide icon, do the proportion: [1920:1080=256:x] -> x=(1080*256)/1920=144

3. finally, use ImageMagick convert command:

   convert -background none -resize 256x144 -gravity center -extent 256x144 image.svg image.ico
