It releases the memory once the final PDF document instance is disposed. The following code snippet explains this. You can optimize the resources by enabling the OptimizeResources property available in the PdfMergeOptions instance. Optimization will be effective only with merge, append and import functions.

Enabling this property will optimize the memory but a difference in time occurs based on the document size. For example, if the PDF document has pages and each page has an image in common. If we import those document pages with the EnableMemoryOptimization disabled by default it is disabled. We will clone the image resource for each page separately.

That leads to the imported document having a huge size when compared to the source PDF. That does not cause any PDF file size issue. Moreover, it does not cause any memory leak issues. So, without any hassle, you can enable the EnableMemoryOptimization property whenever you need this behavior. Refer to the following code snippet to reduce the PDF file size while importing pages from multiple documents.
