What other image processing options in PdfCompressor can reduce file size while improving image quality?
The despeckling option, on the Image Processing page, can sometimes reduce the size of scanned black and white documents while improving image quality. This option, however, can occasionally cause image artifacts so it should be used with caution. The deskew option, also available on the Image Processing page as the option to Automatically rotate scanned pages to proper viewing angle, should improve the overall image quality of scanned bitonal files and slightly reduce file size (assuming the files have not already been skew-corrected).
