I would scan them to TIFF with the software that comes with Windows (Scanner and Camera Wizard?), or whatever software Epson bundles with the scanner. Then create PDFs with pdf995.

I've had good experiences with PDFCreator, which is free (free like beer, maybe speech). It installs itself as a "printer", so anything that can print can send it files to be turned in to PDF.

Depending on the nature of your documents, you may need separate software that does OCR. That is software looks at a picture of text (what a scanner makes) and turns it into editable text like MS Word makes. The full paid versions of Acrobat include an OCR feature, so be mindful not to conflate "make pdf" with "do ocr".

I'd do the same, but use the "print" function of your scanner to print to BullZip PDF.

Bullzip allows you to concatenate the prints into a single PDF.

I used jpg2pdf once. It worked fine.

Oh, not free though, shareware.

A free possibility might be tiff2pdf. Both tiff2pdf and tiffcp are available in cygwin. Haven't used them though.

We use CutePDF at work. Even though we have Adobe, I like it because piggy little Acrobat can be a bit crash happy. Also, it's free.

Cool, y'all. Thanks!
