We encountered a project where we needed PDF to TIFF conversion and we then decided to use Aspose.PDF for .NET. We found that the PDF conversion was very fast, supports multi threading and quality of the output is easily controlled and set to our requirements. It was quick and easy to implement into our project and so far it has made a positive impact for us. Our experience with Aspose products so far is very positive and quality of the product is very high. We will certainly continue to source Aspose components first when needed before looking elsewhere.
