How can I merge multi pdf files with bookmarks?

[Thanh Hai Dang]

Hi, 

I'm using .NET 8 and syncfusion 25.1.35. 

I've attempted to merge multi pdf files. How could I merge with bookmarks handling options such as: merging all bookmarks from input files,  creating new bookmarks from them, removing all bookmarks. 

I've not see any options when merge them.

btw, I've not  see any options to optimize the output file's quality such as : web ready (small), office ready (medium), print ready (large) too.

P/s: The merge options, which I've mentioned, look like in the Nitro PDF application. 

Thanks and best regards,

TH

Hi  Jeyalakshmi ,

Thank you for spending time with my requirements. However, I cannot show anything about bookmarks in your example. 

See the example created for save pdf file in the others format.

Hi Thanh Hai Dang,

We have created a sample for creating new bookmarks in a PDF. Kindly refer to the code snippet for your reference:

PdfDocument finalDocument = new PdfDocument();

Stream documentStream = this.GetType().Assembly.GetManifestResourceStream("MauiGrid.Resources.Pdf.sample.pdf");

Stream documentStream2 = this.GetType().Assembly.GetManifestResourceStream("MauiGrid.Resources.Pdf.Input.pdf");

          

//Create a PDF stream for merging

Stream[] streams = { documentStream, documentStream2 };

          

PdfMergeOptions mergeOptions = new PdfMergeOptions();

mergeOptions.OptimizeResources = true;

//Merge PDF documents

PdfDocumentBase.Merge(finalDocument,mergeOptions, streams);

 

PdfBookmark bookmark = finalDocument.Bookmarks.Add("Page 1");

//Sets the destination page.

bookmark.Destination = new PdfDestination(finalDocument.Pages[0]);

//Sets the text style and color.

bookmark.TextStyle = PdfTextStyle.Bold;

//Sets the destination location.

bookmark.Destination.Location = new PointF(20, 20);

We support removing bookmarks from PDF documents, and you can refer to the UG and KB documentation, as well as blogs, for further details:
