The Optimize PDF tab is used to optimize PDF documents and reduce file size. After the document has been optimized, there are options for routing of the output file. The tab has the following sections:
PDF Automation Server can process images contained within the document using a variety of settings:
Image Compression - Convert any image to either a JPEG, JPEG2000, FLATE, or JBIG2.
Image Quality - Allows the image quality to be adjusted between 10-100%.
Note: This will only affect JPEG or JPEG2000 images as these are the only formats that support image quality settings.
Image Color Space - Choose to either retain or convert the image colors to Grayscale or B&W.
Note: When the retain option is selected CMYK images will be converted to RGB due to a regression bug in Java 1.7.
DPI (Dots per Inch) Resolution - Adjust the image resolution of all images that are larger than the option selected
PDF Automation Server can remove the following objects from within a PDF:
Alternate Images - Removes alternate embedded image dictionaries that are used for high resolution printing to reduce file size. Only visible images displayed on the PDF while viewing will be kept in the document.
Bookmarks - Removes all bookmarks from the PDF document
Document Info - Removes any document information located in the document properties (Document->Document Properties) that would include the following:
JavaScript Actions - This will remove all JavaScript actions from the PDF document but retain any objects that may have had JavaScript actions such as form fields, push buttons, etc...
Embedded Thumbnails - Removes page thumbnails that are stored in the PDF document. Once removed the page thumbnails will just be rendered each time the document is loaded.
Comments - Removes all annotations and comments from the PDF document
Links - Removes all links from the PDF document
Attachments - Removes any attachments that are stored within the document
Form Fields - Removes all form fields that are on the PDF document
Metadata - Removes all additional or extra Metadata from the PDF Document
Unused Resources - Removes resources that are located within the document but are never referenced by any objects in the PDF document.
PDF Automation Server has the following additional options available to further compress the PDF document:
Flatten Comments - Flattens all annotations including text boxes, shapes, highlights, and stamps directly onto the document so that they can no longer be edited.
Note: Annotations such as the sticky note will have comments removed but the image will still be placed on the document
Flatten Fields - Flattens all fields including text boxes, check boxes, radio buttons, combo boxes, list boxes, buttons, and signature fields directly onto the document so that they can no longer be edited. All values within the fields will be flattened as well
Merge Duplicate Images - Merges any duplicate images within the PDF so that all objects are referencing the same image resource rather then multiple of the same resource
Merge Duplicate Fonts - Merges any duplicate fonts within the PDF so that all objects are referencing the same font resource rather then multiple of the same resource
Compress Document Objects - Compresses any additional PDF elements within the document such as page descriptions that have not been optimized by any other process to further reduce file size
Clear Signatures - Removes all signatures that are on the PDF Document but will leave the signature field
Convert to Fast Web View - Fast web view restructures the documents internal structure and content so that the pages load in order. When converting to Fast Web View the content is just reorganized internally. No content is altered or removed so the PDF will be displayed exactly the same as it was prior to conversion.
Converting to fast web view allows large documents to load faster when downloading from a web. Having the document structure and content in a linearized (from beginning to end) order allows a browser to immediately display the first page as the remainder of the document is still being loaded.
Note: In order to see the complete speed benefits the server where the PDF is being hosted must also support page by page loading.
This section determines what happens once the PDF document has successfully been processed. If the processing fails for any reason the document will instead rout the document using the settings set in the Trouble Handling tab.
