Presets
Compression Presets
Choose compression level from presets. If preset is selected all other compression options are ignored.
ColorImageCompression
Color image compression
ColorImageQuality
Color image quality
Color image compression quality. The parameter applies only to JPX and JPG compressions.
ColorImageDownsample
Color image downsample
Enable Bicubic image downsampling and decreases the number of pixels in the color image which in turn makes the file smaller.
ColorImageThresholdDpi
Color image resample threshold
Threshold in DPI to activate color images resampling. ColorImageDownsample property must be enabled.
ColorImageResampleDpi
Color image resample
Color image resolution in DPI after Bicubic resampling. ColorImageDownsample property must be enabled.
GrayscaleImageCompression
Grayscale image compression
GrayscaleImageQuality
Grayscale image quality
Grayscale image compression quality. The parameter applies only to JPX and JPG compressions.
GrayscaleImageDownsample
Grayscale image downsample
Enable Bicubic image downsampling and decreases the number of pixels in the grayscale image which in turn makes the file smaller.
GrayscaleImageThresholdDpi
Grayscale image resample threshold
Threshold in DPI to activate grayscale images resampling. GrayscaleImageDownsample property must be enabled.
GrayscaleImageResampleDpi
Grayscale image resample
Grayscale image resolution in DPI after Bicubic resampling. GrayscaleImageDownsample property must be enabled.

Output PDF should only contain font characters utilized in the original document, and any unused glyphs from all fonts in the document should be removed.
CreateObjectStreams
Create object streams
Create object streams in the PDF file. An object stream represents a stream that contains a sequence of PDF objects. This allows a greater number of PDF objects to be compressed. Property compatible with Acrobat 6/PDF v1.5 and later.
