Optional. Enable this value by adding it to the profile and setting it equal to ON.
| preserve-version | If this value is set to off, PDF Optimizer saves the output PDF document to PDF version 1.7.
If you set this value to “on,” PDF Optimizer preserves the original version of the PDF source document if possible. If you select an option for PDF Optimizer to use when optimizing your source PDF document that will conflict with the current version of the PDF document, PDF Optimizer will ignore your request to preserve the original version of the PDF source document. For example, if you want to use PDF Optimizer to process a PDF source document of version 1.5, and request that the version be preserved and also that the document be converted to PDF/A-3u format, the output will be 1.7 since it's required for PDF/A-3u output. |
| write-output-even-if-increase-in-size | If this value is set to off, if PDF Optimizer finds that the output file will be bigger than the original PDF input file when it is finished processing, PDF Optimizer will not generate an output file at all. Rather, it will write an error message saying that the file could not be optimized.
If you set this value to “on,” PDF Optimizer generates the PDF output file even if the optimization process produces a document bigger than the input file it is meant to replace. |
