Lossless TIF to PDF conversion

Hello,

I want to convert many (multipage) 24bit color JPEG-compressed TIF files (from scanner) to a PDF format, lossless, in order "to gain the Acrobat functions on the TIF".

I thought it was possible to have the PDF as plain "TIF container", but didnt manage that so far without to change the image structure.

Is this achievable? My attempts failed and yelded sometimes much(!) bigger PDF counterparts of the original TIF file. It must be a lossless conversion.

Thanks in advance,

Dani
