How important is file size to you, given that your images are black and white and now encoded about as efficiently as is possible using readily available freeware software? Image files are large, and if you had to scan to grayscale (necessary for any pages that have half-tone graphics or photographs) or to colour, the reulting image files even efficiently encoded would be much larger? Xn_Multi-page_FAX.pdf (983.03 KiB) Downloaded 135 times function (or, probably better, scanning at 400DPI for future scans), or using commercial software to save the existing 600DPI TIFF images with more-efficient JBIG2 compression: the 'lossy' version may be quite effective, although with a slight risk of inserting incorrect characters in places.Īlternatively, Adobe Acrobat Clearscan could potentially shrink the file significantly while also enhancing the text quality, although a reduction in file size may only be obtained for a reasonable run of pages. If that is the case there are options to decrease the size further, but they would mean either accepting lower image quality - though downsampling to 300DPI or possibly 400DPI using the Image > Resize. Anything beyond 30 MB or more, nitropdf crashes.Īre you saying that 90KB per page, 9MB per 100 pages is still too large? I have Nitropdf and tried to optimize with 300 dpi etc, but since the starting size of pdf that got created with xnview is around 122 MB, it crashes.
