Hi,
Hope you are doing well.
Note the process of converting PDF to TIFF consists of two parts. Firstly Spire.Pdf will convert Pdf file to images. Then it will use C# code to convert images to Tiff, and this code is not related to our product.
Since the size and complexity of your Word file, and you set 300DPI for the images(if you set a smaller value, the process will be faster), when converting to images with Spire, the time is about 90s on my computer(Win7 64bit, RAM 8GB), and this is actually normal. I am afraid there is no good way to improve the time with Spire at present.
The most of the conversion time(about 130 seconds) is spent on the second part, and this part is not related to Spire.Pdf, and we cannot do anything about that.
Hope you could understand.
Best wishes,
Amber
