Converting PDFs to TIF Files

Overview

Ephesoft uses Imagemagick® for converting PDFs to TIF files.

Imagemagick® uses the following command syntax:

convert.exe [parameters for opening the file] input file [parameters for saving the file] output

Since PDFs are opened at 72 DPI by default, open with a higher resolution. Recommended command:

convert -density 300 input.pdf -compress group4 output.tif

Where:

Imagemagick® uses Ghostscript behind the scenes and may slow the process on large PDF files. It is also possible to use Ghostscript to convert PDFs to TIFFs.

Command example:

gswin64c.exe -dNOPAUSE -r300 -sDEVICE=tiff24nc -dBATCH -sOutputFile=output.tif input.pdf
convert output.tif -compress group4 finaloutput.tif
  • -r300 specifies the DPI (value is configurable)
