The optimization profile producing a minimal file size
This profile optimizes the output PDF for minimal file size. This is achieved by using a varied palette of image compression algorithms, appropriate resolution setting and higher compression rates at the price of slightly lower image quality.
The output file size is further reduced by converting Embedded Type1 (PostScript) fonts to Type1C (Compact Font Format) and removing metadata and output intents (see RemovalOptions). Also Spider (web capture) information is removed.
Images above 182 DPI are down-sampled and recompressed to 130 DPI. This leads to smaller output files. The property ResolutionDPI has influence on both values.
When an image is recompressed, the Balanced strategy is used; this can be overridden through the property ImageRecompressionOptions.
With this profile, the output PDF version is updated to PDF 1.7 or higher and PDF/A conformance removed.

| ResolutionDPI | The target resolution of images in DPI The target resolution in DPI (dots per inch) for color and grayscale images. Images with a resolution above ThresholdDPI are down-sampled. Valid values are in the range 1.0 to 10000. If , then resolution setting is disabled. Default: 130. |
| ThresholdDPI | The threshold resolution of images in DPI. The threshold resolution in DPI (dots per inch) to selectively activate downsampling for color and grayscale images. Valid values are in the range 1.0 to 10000. To deactivate down-sampling of images set ResolutionDPI to . Default: 1.4 times ResolutionDPI. |
