We are developing .Net components to do all what you wish with documents in PDF, DOCX, RTF, HTML, Images and other formats.
Document .Net allows your App to do all with documents: Create, Load, Modify, Convert, Merge, Sign Digitally, Find and Replace, Do Reporting, Rasterize to Image.
"Intelligize evaluated several components but none of them provided required conversion accuracy and were overpriced. Finally, they tested HTML to RTF .Net from SautinSoft and found the component to be the best for their requirements. As a result, the developers were able to add the conversion capability in a fraction of the time that it would have taken without access to the library."
