Compression of TIFFS in PDF

Aspose.PDF Product Family
1

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!

Anthony

Dear Anthony,

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