This is what worked for me
This is what worked for me and would be the easiest to run.
find . -type f -name "*.svg" -exec bash -c 'rsvg-convert -h 1000 $0 > $0.png' {} \;
rename 's/svg\.png/png/' *
This will loop all the files in your current folder and sub folder and look for .svg
files and will convert it to png with transparent background.
Make sure you have installed the librsvg and rename util
brew install librsvg
brew install rename
