    Merge PDF Files

    It is a Windows library that merges standard PDFs into a final PDF

    The library is intended for developers, for inclusion in desktop applications or server services. There are lots of SDKs on the market creating (merging) PDFs (almost all of them have limitations). Our Windows library (MergePDFByNMI.dll) only merges standard PDF files (there are several PDF formats). You can send the input PDFs (by file name or by byte array) and you can have the final PDF (saved on a file or get back on a byte array). The library calls can be synchronous or asynchronous. We want to give you a benchmark, the library was used to create a PDF from single page(scanned) image by an OCR SDK (it is not included in our library, you can use any on the market): 20,000 Images (the OCR SDK creates single page PDF text searchable, running 50 threads) in 80 minutes. The size of the final PDF searchable was 800Mb. If you download the library, we provide a sample which cover all the scenarios possible (synchronous and asynchronous).
