confirm you can get the size by command : stat -c %s yourfile, otherwise, replace by :

Code:
ls -l $pdf | awk '{ print $5}'

Code:
for pdf in *.pdf
do
   Spdf=$( stat -c %s $pdf)
   xpdf=${pdf/.pdf}.xpdf
   if [ -f $xpdf ] ; then
      Sxpdf=$( stat -c %s $xpdf)
   else
      echo "$xpdf is not exist"
      exit
   fi
   
   # delete the bigger one 
   if [ "$Spdf" -gt "$Sxpdf" ]; then
      rm $xpdf
   else
      mv $xpdf $pdf
   fi
done
