Now that we have everything set up, let’s move on to the actual code for deleting bookmarks.

Step 1: Define the Document Directory

First, you need to specify the path to your PDF file. This is where your original PDF is located and where the updated file will be saved.

string dataDir = "YOUR DOCUMENT DIRECTORY";

Step 2: Open the PDF Document

Next, you’ll open the PDF document that contains the bookmarks you want to delete. Use the following code to load your PDF:

Document pdfDocument = new Document(dataDir + "DeleteAllBookmarks.pdf");

Step 3: Delete All Bookmarks

Now comes the crucial part—deleting the bookmarks. Aspose.PDF makes this incredibly simple. Just call the Delete() method on the Outlines property of the document:

pdfDocument.Outlines.Delete();

Step 4: Save the Updated File

After deleting the bookmarks, you need to save the updated PDF file. Specify a new file name or overwrite the existing one:

dataDir = dataDir + "DeleteAllBookmarks_out.pdf";
pdfDocument.Save(dataDir);

Step 5: Confirm the Deletion

Finally, it’s always good practice to confirm that your operation was successful. You can print a message to the console:

Console.WriteLine("\nAll bookmarks deleted successfully.\nFile saved at " + dataDir);
