I'm not aware of a KDE4 GUI software that does that, but Image Magick 
does the job very well at the command line.
find -iname "*.jpg" -exec mogrify -resize W[%]xH[%] {} \;

This will resize all jpg files in the directory tree starting at the 
current directory to the size or percentage you specify.
If you want to resize files in a single directory, you can use:
mogrify -resize W[%]xH[%] *.jpg

Instructions on how to use mogrify are here:

See the convert command to (it's also part of Image Magick).

Just out of curiosity, what do you use in KDE3 to do this?
