I had scanned 11 sites of a document in black and white and exports it as an pdf file. With two different known apps I got a file size of about 8MB. I tried different solutions with ColorSync filter or ghostScript commands but the pdf size does not shrink noticeable.

With scans from a printer I got pdf files with about 10 percent of that size without loss of quality. Does anyone knows how to reduce a large pdf file?

    How did the app scan the document? Was it an image or was it text? Same question for the ptinter?

  • 11 pages of pdf at 8MB is tiny already. What are you hoping to gain?

    I scanned the same document later with my printer and got a file size of 1MB for b/w and 300dpi. I looked into the file from the app and see that the first page was an image with RGB 8 pits per component and a size of 3555x2522 for an a4 page. With the app I could only set up black and white but this seams not to work very well. The document ist only text.
