"There's an app for that."  :o)

Imagemagick is a Swiss Army Knife for doing operations on image
files from the terminal, including format conversions.  I use this
batch script, with file format extensions changed as necessary, for
batch conversions:

#!/bin/sh
# svg to png is only an example, change as needed
for f in *.svg;
do
echo "converting $f"
convert "$f" "${f%.svg}.png"
done

Save the above text in a plaintext file, give it a name with a .sh
extension and make it executable.  Copy it to the directory your
target files live in, run it with ./script-name.sh and watch the fun.

The above should work on any UNIX-like OS.  According to the
Sourceforge page, a package for Microsoft is also available.
