Is PdfCompressor useful on files that are completely generated, i.e., contain no image streams?
Even though PdfCompressor is most useful on files that contain image streams, it can sometimes be very useful in compressing files that do not contain image streams. In addition, PDF files are not always as they appear. For example, it may appear that a generated PDF document such as a company invoice does not contain any images when it actually does contain embedded image streams, e.g., company logo. When in doubt, try running the file through PdfCompressor (in default mode) to see if there is any file size reduction. If the file appears to be generated but the file size seems very high, in excess of 100 KB per page, we recommend first trying PdfCompressor using the default settings (e.g., stream compression mode). If this does not reduce the file size, try PdfCompressing the document in raster mode which is shown on the “Image Processing >> PDF Input Processing” page as the Rasterize each page before compressing option. Leave the other rasterization options in their default settings.
