I agree, one will lose quality converting tiff to jpg back to tiff.
We experienced with batch converting tens of thousands of tiffs to PDF
for a newspaper digitization project. For us we found that though Image
Magick does convert, the output PDF file sizes were huge to retain a
decent quality PDF. We ended up using poppler 0.20.5 on mac.
In separate projects we have used Adobe Bridge to batch output a tiff
image per page in PDF.

Yes, converting from JPG to TIFF would have the quality of a JPG and
(I believe) the file size of a TIFF.

I'm by no means an expert in the math behind image format conversions...
but:
When converting to TIFF-to-JPG, TIFF is uncompressed formatting and
JPG is
compressed format.
When back converting, wouldn't the original quality of TIFF would be
lost,
converted only to the quality of the last JPG (with degradation on
each time
this process occurs)?

If you can stand an extrastep, Ed, there are tools to convert PDF to jpg
images, and from there it shouldn't be too hard to get TIFF output. Do a
search for "convert PDF to image" to get started. There are tools
that are
not online only, which I'm pretty sure is what you're after.

Hi All,
I have a need to batch convert many TIFF images to PDF. I'd then like
to be able to discard the TIFF images, but I can only do that if I can
create the original TIFF again from the PDF. Is this possible? If so,
using what tools and how?
tiff2pdf seems like a possible solution, but I can't find a
corresponding "pdf2tif" program that reverses the process.
Any ideas?
Edward
