Merge / combine two PDFs

I´m using the API via the COM interface and there is NO problem to print whatever into a PDF from e.g. any report within my app.
However I would like to merge(?) or combine(?) a second PDF like e.g. some company paper layout or watermark. I have no idea, if this is called merging, combining or overlaying or whatever, what makes it even harder to google a solution.
To make it even more clear; Two PDF pages shall be merged to one output page, where the printout overlays the background from an existing PDF, all of this controlled through the API.
E.g. the Amyuni commercial PDF converter does have such a feature.Does anyone have an idea, if PdfCreator can do this and any hint, how ...?
Thanks in advance

Did you ever get a resolution to the merging of PDF files? We are look at overlays for invoices/delivery notes etc. but the image of the invoices, ie colomn lines are erased by the lines of text across the page.

Any help or ideas would be helpful.




You could use another open-source program for this - pdftk (the PDF Tool Kit). Taken from 'pdftk --help':

       If PDF is electronic paper, then pdftk is an electronic staple-remover,
       hole-punch, binder, secret-decoder-ring, and X-Ray-glasses.  Pdftk is a
       simple tool for doing everyday things with PDF documents.  Use it to:

       * Merge PDF Documents
       * Split PDF Pages into a New Document
       * Rotate PDF Documents or Pages
       * Decrypt Input as Necessary (Password Required)
       * Encrypt Output as Desired
       * Fill PDF Forms with X/FDF Data and/or Flatten Forms
       * Generate FDF Data Stencil from PDF Forms
       * Apply a Background Watermark or a Foreground Stamp
       * Report PDF Metrics such as Metadata and Bookmarks
       * Update PDF Metadata
       * Attach Files to PDF Pages or the PDF Document
       * Unpack PDF Attachments
       * Burst a PDF Document into Single Pages
       * Uncompress and Re-Compress Page Streams
       * Repair Corrupted PDF (Where Possible)`

Please use the the pdfforge.dll coming with PDFCreator. The perfect way to merge pdfs.

Hi there,


I still don't see where to merge documents into one multi-page pdf. Is there this ability (without coding or dll's or any such hassle).






there is an example for merging with vbs in the COM folder in your PDFCreator install path.

To merge several PDFs "manually" you need to press wait and collect instead of save in the pdf creation dialog. After you collected all the PDFs you want to merge, click on Document->Combine all in the PDFCreator print monitor.





Is it possible to do this via VBA and if so can you provide an example?

I’m coming at this same issue - I can print to PDFcreator from an Office (MS Access Report) VBA script, but i’d like to attach multiple PDFs already saved from elsewhere onto the end of the PDF I’m creating. Is there a way to pass a PDF (pre-made) into the print queue, or handle it as a merge after creating the new PDF?  (I don’t think I can print a PDF from Access natively, so I would have to handle a new application printing to the PDFcreator printer, rather than the printer of choice from that separate app)

A VBA script example would be lovely.

have a great day
