Simple bash script to batch convert svg files into pdfs. It doesn't mess with your fonts and requires rsvg-convert.

svg2pdf.sh

#!/bin/bash
# rsvg-convert is inside librsvg2-bin in ubuntu
for SVGFILE in *.svg;
do
	SVGNAME="${SVGFILE%.*}";
	rsvg-convert -f eps -o "$SVGNAME.eps" "$SVGFILE"
	ps2epsi "$SVGNAME.eps"
	ps2pdf -dCompatibilityLevel=1.4 -dEmbedAllFonts=true -dSubsetFonts=true -dEPSCrop "$SVGNAME.epsi" "$SVGNAME.pdf";
done
wait
rm *.epsi
rm *.eps
