Regretfully the ticket is not resolved yet as it needs additional investigation and there are other high priority issues in the queue as well. However, as a temprary solution, convert pdf->docx on separated pages. Such conversion takes 20 minutes for all the 2225 pages:

 try {
            Document finalOutput = new Document(dataDir + "dstStream.pdf");

            //???
            //finalOutput.getPages().add(finalOutput.getPages());

            DocSaveOptions opts = new DocSaveOptions();
            opts.setFormat(SaveFormat.DocX);
//            finalOutput.save(dataDir + "output.docx", opts); // this part is taking time

            PageCollection pages = finalOutput.getPages();

            for (int i = 1; i <= pages.size(); i++)
            {
                Document temp_doc = new Document();
                temp_doc.getPages().add(pages.get_Item(i));
                temp_doc.save(dataDir + "tmp\\" +i+"_Converted.docx",opts);
                System.out.println("Converted page - " + i);
                printMemoryStatus();
            }


        } catch (Exception ex) {
            ex.printStackTrace();
        }

Additional question is for the code line: finalOutput.getPages().add(tempDocument.getPages());
This will duplicates all the pages, so this line is probably mistake.

Ok Thanks.

But this seems time consuming. Please prioritize PDFJAVA-38858 as well. Our clients are waiting for this issue to be fixed since more than 8 months.

Thanks,

Asad, We tried the approach you sent but this altered the layout of the elements like charts, alignment of contents within a cells etc. So, we have reverted this.

If there’s any other approach. Please suggest.

Thanks,
