No problem.
If you want to save space, then try the Multivalent compress function (get the
jar here). I've had PDFs that went from 24MB to less than 500kb:
$ java -cp Multivalent20060102.jar tool.pdf.Compress -jpeg -noalt -nostruct INPUT.pdf
This will save the output in INPUT-o.pdf, but you can use -inplace to simply overwrite the input file.
