pdf compression


Senior Member

I would like to find a way to compress pdfs created by my scanner. I always choose the lowest dpi (I think I can't go lower than 150) and the smallest file size. The problem is that I need to upload these pdfs on a site that requires sizes of no more than 300KB. After I digitally sign the pdf, it often happens that it exceeds this maximum size.

I tried using a program called free pdf compress, but, weird enough, the compressed file turned out to be even bigger than the original size, regardless of the options I chose.

As these are private documents, I wouldn't like to use public sites to compress the pdfs. So I'm looking for a good program that does that.

Any suggestions? Commercial or not, although I'd prefer freeware.

This one does cost some money ($50) I think but does make smaller PDFs. CutePDF - Convert to PDF for free, Free PDF Utilities, Save PDF Forms, Edit PDF easily. You could even try the free Cutepdf writer, which is an emulated printer. So basically
  • Scan in your file to pdf
  • Then "print" it to the cutepdf writer and see if that reduces the size
