Sure, but these are especially small photos -- are these born digital?
Lossless scans of pretty small photos are frequently well over 100MB, and
it takes hardly anything to get a 1GB scan. It costs a fortunate to treat a

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

Image Magick can do it, you need Ghost Script installed though. I'Ve done
this with multi layer TIFs and multi page PDFs.

Imagemagick's convert will do it both ways.
convert a.tiff b.pdf
convert b.pdf a.tiff
If the pdf is more than one page, the tiff will be a multipage tiff.

Hi, you'll notice from the language you use to describe your use case,
that you use the word convert to describe what you're doing to the
original TIFF images. Once you're done producing a derivative from those
TIFFs, the only way back to the original TIFFs is to go back to the
actual originals.
This works sometimes. Well, it does give me a new tiff file from the pdf
all of the time, but it is not always anywhere near the same size as the
original tiff. My guess is that maybe there is a flag or somethign that
woulf help. Here is what I get with one fil:

Actually, I'm mistaken. It didn't ever work. :-(. I do get a tiff, but not
the original. I looked at the wrong files.

What's your use case in this scenario? Do you want to provide access to the
PDFs over the web or are you using them as your archival format? You
probably don't want to use PDF to achieve both objectives.

Hardy,
You may very well be correct, but some programs claim to keep the original
image data unaltered [1], so I was hoping that was the case (basically it
would put some sort of wrapper around the tiff. Tiff2pdf on my Ubuntu box
