PDF Concatenation Error

Hi,
Please find attached 2 pdf files. When I concate them resulting file is not been able to open.

Can you tell me what is wrong?

I am using following code.

Dim pdfEditor As New PdfFileEditor()
pdfEditor.Concatenate(“D:\file1.pdf”, “D:\file2.pdf”, “D:\merge.pdf”)
MsgBox(“Done”)

Hi Saumil,

I have tested this issue using the latest version at my end and it worked fine; the output file was created and opened successfully. Could you please try to use the latest version at your end as well? If you still find the same issue then please share the following details: OS and .NET Framework version. We’ll further investigate this issue and guide you accordingly.

We’re sorry for the inconvenience and looking forward to help you out.
Regards,
