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