Our interest was in Aspose.Pdf for .NET development, and we found it very useful, but also other tools (we didn’t test yet) seem to be very useful as well.

Aspose.Pdf is very helpful in dealing with any PDF file, and includes a variety of methods (including OCR which has a fantastic performance and accuracy)

Finally, you can treat Aspose.Pdf for .NET as a time and money saving solution. Enjoy!
