HEIC to JPG using terminal (in macOS)

heic2jpg.sh

# Add this to your .zshrc or .bashrc
# Use it by simply calling `heic2jpg pwd/picture1.heic pwd/picture2.heic pwd/picture3.heic`
# Only compatible with macOS. You can also change line 21 to make it compatible with something else.
# If you decide to delete source files, those will be in the bin, not deleted as with `rm` command.
# You will need imagemagick bin to convert the pictures: `brew install imagemagick`
