The PDFs coming out of the NeatWorks for Mac are huge. However, the PDFs generated by my ScanSnap are less than a third of this size. I know this because ScanSnap stores them into a folder and NeatWorks then pulls it from there - without the option of deleting them after!
Anyway, the only thing that NeatWorks should be adding is the OCR text - so why the massive bloating??? Yet another flaw.
