Compression of TIFFS in PDF

We are taking black and white document scanned as TIFF files and converting them to PDF. After the conversion process is complete, the generated PDF is more than 3 times the size of the original images.

For example, today I had two TIFFs of size 56K and 34K respectively. After conversion, the new document was 312K. We have adjusted the CompressionLevel setting on the PDF object to various values of 7-9, but none of them seemed to have any impact. Our generated document is always about 312K.

What can we do to generate a PDF that is comparable in size to the sum of our original images?

Thank you!


Dear Anthony,

Can you please provide the TIFF file and let us test it?

Here are the two TIFFS I used.
