The Optimize PDF File step compresses the PDF and reduces the overall file size. It helps to reduce the amount of storage space that the PDF file takes up on the server. Additionally, it also helps to reduce the time to import and export projects.

Properties

Settings

Property		Description
File Inputs	FileData	File Data is the Data Type used for file handling and is stored as a Byte Array within a Flow. For more information, refer to File Type Overview.
File Inputs	FileReference	File References provide a way to access a file through a Flow or process without processing the file in memory. For more information, refer to File References. Using FileReference can sometimes lead to larger file sizes than expected.

Advanced

Property	Description	Default Value
Compress Image > Image Quality	Allows to lower the image quality within the PDF. (Value in percentage)	50
Resize Image > Max Resolution	Allows to reduce the DPI of the images within the PDF	300
Image Compression Version	Standard - Standard PDF compression balances file size and quality and may take longer to compress than fast compression. However, it can produce a higher-quality output while reducing the file size. Fast - The fast version of PDF compression prioritizes speed over maximum compression, using faster and simpler algorithms that may result in some loss of image quality for faster processing. Mixed - This version of the PDF compression algorithm uses a combination of both standard and fast compression techniques.	Standard
Link Duplicate Streams	Duplicate content streams found within the PDF document will be consolidated into a single, shared stream.	Enabled
Allow Reuse Page Content	Duplicate objects and resources can be eliminated or consolidated, which can significantly reduce the file size of the PDF document.	Enabled
Unembed Fonts	The unembed fonts method removes all embedded fonts. This decreases the document size, but the document may become unreadable if the correct font is not installed.	Enabled
Return Original File on Error (v9.6+)	If an error occurs during the optimization process, this setting can allow the file to be recovered and reused. Often useful for PDFs that are corrupted.	Disabled
