Hi,
Below is my answer to your question about commercial Spire.Doc and Free Spire.Doc.
At first, there are some limitations in the free version. The free version is limited to 500 paragraphs. This limitation is enforced during reading or writing files. When converting word documents to PDF files, you can only get the first 3 page of PDF file. Second, we have no plan to update the free version, so it is not very stable. As for the commercial version, it has better optimization and more features than the free version. The new features and fixes will only be included in commercial version. Any question, feel free to contact us.
Sincerely,
Mike
