    I am only able to keep the image readable at 40 - 50 kb but unable to reduce further without losing significant quality using my Photoshop and other online image resizing services.

    Upload them one at a time to avoid the 5MB file limit?

    That's not an option. I need to create a single PDF file to upload it all in one go with all documents along with my digital signatures.

    This is for the purpose of creating a new company.

    These are black and white pages? What's the point of making them too small (=unreadable)?
    I have scanned thousands of pages, jpg (for pages with color, pics, graphics) is usually around 70kb or more per page, if it has to be readable.

    The GIF format seems to be better suitable for your needs: 20-30kb per B/W page, at a reasonable resolution.

    You don't even need expensive software to make Pdf's out of your GIF's: "FastStone Image Viewer" can do it for free. (Just select the files, then select "Create - Multi-page File" and select PDF format). GIF is also much better readable when you zoom in on your (B/W) text.

    Of course, the best solution would be to OCR the text, which would leave you with only 4kb per page, but that's a whole different topic...

    As I said, I need it for incorporating a new company which has 10 subscribers in the company. Have to upload their declaration, affidavits etc in the single PDF.

    I am just trying to find out if it is possible to reduce sizes of B/W images since there isn't much color in it. Of course I won't try to incorporate new companies again with 10 members but have to do this.

    I don't have problem making PDF, Just need to know how to reduce image size which is the real problem here??

    Can't do OCR. I am told only scanned images are approved. It's okay if it isn't possible. I just gotta pay a little penalty amount.

    But thanks everyone for trying to help.

    Just for fun, I downloaded your sample jpg, then converted it to B/W and saved it as GIF. File size was 14kb.
    You said only scanned images were approved, but scanned images saved as GIF are still scanned images :)

    @kaljukass: That's a pretty remarkable quality image with so much compression. Thanks for sharing.

    I generally use Compressor.io to compress the images.

    Processing the file by OCR results in very small page weight (~15 to 30 KB per page) in the resulting PDF. Here are two examples in a zip.
