A website said my PDF file is too large to upload. Can I make it a little smaller?
You can do that with Acrobat as well.
Do you have Acrobat? Another option would be http://createpdf.acrobat.com/ but I am not sure if it can do the optimizing.
Rescan the documents at a lower resolution and scan greyscale rather than color. This should shrink the pdfs considerably. Many Scanners come with graphics programs that can convert the scans you have already made, but if not as Pat mentioned Acrobat can do this for you.
