KWord is a KDE application that has a pdf “import” feature which lets you import either entire pdf documents or just a few pages from a pdf document while preserving the formatting! Of course - this only works for pdf documents which are not scanned images of pages.
sudo apt-get install kword
KWord - file menu Start the import using the “File” -> “Import” option in the main KWord menu.
Kword - import pdf After you select the pdf file to be imported, you will see a window like the one above where you can specify the pages you want to import. After the edit you can save it .doc or open office standard format.
