Top Features


  1. Save time and cost of the product development. The writing of own classes to support PDF, RTF and DOCX formats in C# requires a lot of days of hard work and takes approx 300 000 C# code lines. Document .Net will save a lot of my time and I'll need only to add the reference to "SautinSoft.Document.dll" and write 5-7 C# code lines.

  2. The one product provides me by set of API to create, load, parse, convert, modify documents in various formats at once: DOCX, RTF, PDF, Text.

  3. Because of this is absolutely standalone .NET library, my clients don't need to have Adobe Acrobat, MS Word or other software.

  4. My software will have the one of the fastest API to process documents. At a machine with Intel Core i5-3337U and 4GB of RAM the Document .Net generates a simple DOCX document (one page filled by formatted text) without saving it to HDD:

    • 1000 documents by 0.45 sec.
    • 10000 documents by 3.61 sec.
  5. I can select a desired edition between: Total and Standard. This saves my money. Let's us say, that I'm looking for only the API to create or parse DOCX and RTF and don't need PDF format. Given this point, I can purchase the "Standard" edition of Document .Net. It's much cheaper than competitor's price.

  6. The one time price. I pay a one time and can use «Document .Net» for a whole life without any additional fees. My license will never expires.
