Advanced Options

The advanced 'Compress PDF' flow action parameters are detailed below:

  • Compress Images: Contained images will be compressed, aligned to the value of the 'Image Quality' property.
  • Image Quality: Sets the quality for compressed images: 1 > 100
  • Max Resolution: Specifies the maximum resolution of images (dpi), if the image has a higher resolution it will be scaled dynamically.
  • Resize Images: If 'Compress Images' and 'Resize Images' are enabled, images will be resized where the image resolution is greater than the specified 'Max Resolution' property.
  • Remove Private Info: Remove private information from the PDF document, i.e. page piece information.
  • Remove Unused Objects: Remove all unused objects (i.e. objects which do not have a reference) are removed from PDF document.
  • Remove Unused Streams: Remove all unused resources from the PDF document.
  • Link Duplicate Streams: Link duplicate streams and store them as a single object. This can decrease document size in some cases (for example, where the same document was merged multiple times).
  • Allow Reuse Page Content: Page contents will be reused when the PDF document is optimized for equal pages.
  • Unembed Fonts: Remove all embedded fonts. The document size will decrease but the document may become unreadable if the correct font is not installed on the user's machine.
  • Flatten Annotations: Flatten all annotations contained within the PDF document.
  • Delete Annotations: Delete all annotations contained within the PDF document.
  • Flatten Fields: Flatten all fields contained within the PDF document (AcroForms only).
