[Solved] TIF to PDF: huge file size

Post by Peter2 »

I converted TIF to PDF.
Filesize of TIF: 150 - 250 kB
Filesize of PDF: 17 -18 MB

And changing the settings (LZW, FAX, ZIP, ..) has no result - all the files are the same, only date and title are different.

Peter

PS: Optimizing the files with PDF Tools reduces the size vom 17 MB to 310 kB.

No, a black/White scan with 400 TIF.
