I've spent the day working on a heavily-illustrated scanned book, OCRing it in Finereader then adding some finishing touches in Adobe Acrobat 4 (ancient version but it still works.) The problem was, Finereader kept crashing, the whole PDF was so large. So when a page would need tweaking, I would re-OCR that individual jpeg and insert that into the PDF in Acrobat. After hours of tweaking, I thought I had great results, but then I decided to try viewing it in two-page view so that I could see both halves of an illustration on two pages. And then found that pages that I had re-OCRed were displayed at a different size than the original OCRed pages. The actual images are the same size, but Acrobat is interpreting them as being different because it thinks that they are different DPIs.

So, is there a utility that I can use to make all pages in a PDF be read as a specific DPI?
