Crunching pdf files
Here’s something I’ve noticed; I run Linux and I found that if I have a pdf file and I convert it to PostScript thus:
then I convert back to pdf
I often get a smaller pdf. Most recently, it went from 312K to 229K, a reduction of about 25%. The reduction is often much bigger, or smaller… you can also try running ps2ps on the intermediate ps file before converting back to pdf.
Not too bad — it got the file under the file size limit for my freebie webserver and I was able to upload it.
Key point — this does not downsample the pdf. If downsampling is OK, look here.
