Commented Jan 3, 2019 at 18:28As @VetrivelPS mention, adding more information to this answer would have been useful. Especially the version of APIs used.
Commented Aug 6, 2019 at 20:50 It's removing all headings, not considering images inside doc files. Commented Oct 21, 2019 at 5:49@cody123 of course it doesn't because it attemts for fix very specific case the OP had and doesn't even attempt to profit future visitors.

Commented Aug 12, 2016 at 7:46There are several steps here:
I don't know if POI will do step 2 for you. I'd recommend something else, like iText.

I was already puzzled as to where to find something PDF related in the POI library. Duffymo is correct in the steps he listed. In a similar situation I use 'WordML' (Word 2003 xml format) that is transformed into FO and then rendered using Apache FOP. There are other possibilities, including OpenOffice API. Search through StackOverflow and you'll find plenty of questions/answers about Office2PDF.
Commented Jun 6, 2011 at 10:59As a side note, it's also possible to read content on-the-fly directly from a Word/Excel content stream instead of reading it from the filesystem and serializing it to disk, for example when retrieving content from CMIS repositories:
//HWPFDocument docx = new HWPFDocument(fs); HWPFDocument docx = new HWPFDocument(doc.getContentStream().getStream());
(doc is of type org.apache.chemistry.opencmis.client.api.Document and in this case I adapted your code to retrieve a word file from an Alfresco repository by means of opencmis and transformed it to PDF)

All of the answers above will fail if the document has images. I would not suggest you to use apache poi since its library to convert word to pdf have been discontinued now. As of today I don't think that there is any open source library which do the conversion (they require some dependencies like some need MS word to be installed, etc). The best way I could think of (it will only work if you are deploying project on linux machine) is that install Libre Office (open source) in the linux machine and run this :
String command = "libreoffice --headless --convert-to pdf " + inputPath + " --outdir " + outputPath; try < Runtime.getRuntime().exec(command); >catch (IOException e)answered Sep 14, 2022 at 3:32 Anmol Jain Anmol Jain 394 4 4 silver badges 14 14 bronze badges
