I have some great experience with iText (now, I'm using 5.0. Also if you're going with another tool check what kind of an engine they have to power the pdf rendering, it could happen they are using gs for it like for instance LeadTools does. and prefix.ps code is here: > putĪnother thing about this sdk is that it's open source you're getting both c and ps (postscript) source code for it. It would convert your PDF into the high res G3 TIFF. In production conversion is done using the gsdll32.dll but if you want to try it use the following command line: gswin32c -dNOPAUSE -dBATCH -dMaxStripSize=8192 -sDEVICE=tiffg3 -r204x196 -dDITHERPPI=200 -sOutputFile=test.tif prefix.ps test.pdf And we have quite a few of them coming during the day. How can I change it Thanks in advance for your help. My default settings the one PDF containg five pages will be exported to Five PDF-fiels, One pager per TIFF.

What works fine for us is ghostscript, last versions are pretty much robust and do render correctly majority of the pdfs. I need export/ Convert a PDF File with multipe pages to one TIFF-file with multiple pages. From my experience the best tool you can have is Adobe PDF SDK, the only problem with it is its insane price.

We here also doing conversion PDF -> G3 tiffs with high and low res.
