PDF Document Management 16: PDF Optimizer

PDF Optimizer provides some settings for POSSIBLE reducing the size of PDF files with large size.  The settings are comparable to the settings that are available when you create a PDF file using PDFill PDF Writer.

If PDF Optimizer doesn't work, open your PDF document inside Adobe Reader. Then, print into a new PDF using PDFill PDF Writer with PDF Optimization.

Here are the steps on how to use the PDF Optimizer:

1. Choose Document Menu >  Select a File for More Operations > PDF Optimizer

or click PDF Optimizer Button in the Document Toolbar.

2. Select a PDF to be optimized. The file size of the input file will be displayed.

3. Here is the dialog of PDF Optimizer's Properties:

PDF Output Settings:  The default value is Prepress.

PDF Resolution (dpi): Sets the resolution for pattern fills and for fonts that must be converted to bitmaps. The default value is 300 dpi.

Max Inline Image Size (Bytes): Specifies the maximum size of an inline image, in bytes. For images larger than this size, GhostScript will create an XObject instead of embedding the image into the context stream. The default value is 4000.  It may be advantageous to set a small value if the source document is expected to contain multiple identical images, reducing the size of the generated PDF.

Auto Rotate Pages: Controls the automatic orientation selection algorithm. There are 3 options: None Page, All Pages and Page by Page; the default is All Pages.

Process Color Model: Sets the color space to be used for device-dependent colors in the PDF output. There are 3 options: Device Gray, Device RGB, or Device CMYK; the default value is Device RGB.

Compress Embedded Fonts: Defines whether the embedded fonts will be compressed in the output. The default value is true; the false setting is intended only for debugging.

4. Click the button Optimize and save into a  new PDF file. The output file size will be displayed after the optimization.
