Yes, Aspose.Words and Aspose.Pdf support this feature. We have developed a plugin using Aspose.Words and Aspose.Pdf to allow you to import Word and PDF documents to the content editor of a WordPress post or page. Please check the following links for more details.
The only restriction at the moment is, you will not be able to import images from a PDF (only text is supported in case of PDF files). Aspose.PDF API supports both text and images and next version of the plugin will import both text and images for PDF files also. Our team is working on improving the plugin to support this feature and it will be available soon.
Thank you for your response. Do you have an approximate date for when the next version of the WordPress plugin which will import images from the pdf will be released?
Our plugins team has included this update to their current week's plan, however, we will share a concrete ETA in next 24 hours.
Updated version will be available within this week.
