SwiftView creates high-quality raster PDFs, but this can result in long conversion times for large files. To reduce the conversion time for PDFs, try using G4 compression instead of JBIG2. Please note this may also result in a larger output file.
To change the compression method in SwiftView Pro, open the Export menu, open the Options menu, and then select “Group 4 (lossless) from the compression drop-down menu. To change the compression method in SwiftConvert, add the “set printcompressformat g4” command to your ini file. For instructions on how to use the ini file, please refer to this article.
