Size of Document grows exponetionaly

We have PDF for Java (version 11.7) and Words for Java (version 16.6)

We use the following code to create docx files from a pdf.

Document doc = new Document(“c:\2016 Director and Officer Questionnaire.pdf”);
DocSaveOptions saveOptions = new DocSaveOptions();
// Set output file format as DOCX

doc.save(“c:\2016 Director and Officer Questionnaire .docx”, saveOptions);

The resulting file is about 300k.

When we use Words api to do a compare and save the document the document size explodes to over 5 meg.

Compare code.

Document docA = new Document(“c:\2016 Director and Officer Questionnaire.docx”);
docA.compare(docB, “user”, new Date());

Hi Paul,

Thanks for your inquiry. To ensure a timely and accurate response, please attach the following resources here for testing:

  • Your input documents.
  • Please attach the output Word file that shows the undesired behavior.
  • Please create a simple Java application (source code without compilation errors) that helps us to reproduce your problem on our end and attach it here for testing.

As soon as you get these pieces of information ready, we'll start investigation into your issue and provide you more information. Thanks for your cooperation.

PS: To attach these resources, please zip them and Click 'Reply' button that will bring you to the 'reply page' and there at the bottom you can include any attachments with that post by clicking the 'Add/Update' button.

I"m uploading all of the documents.

Documents (A and B) docx files were created from attached PDF files using Aspose PDF.

The resulting document is (comparedoc.dox) 428 times larger than either one of the original files.

This is the code used to convert from PDF to DOCX.

String path = “c:\pdffonts”;
java.util.List list = com.aspose.pdf.Document.getLocalFontPaths();




Locale.setDefault(new Locale(“en”, “US”));
Document doc = new Document(“c:\DocumentA.pdf”);
Document doc2 = new Document(“c:\DocumentB.pdf”);

// Instantiate Doc SaveOptions instance
DocSaveOptions saveOptions = new DocSaveOptions();
// Set output file format as DOCX

doc.save(“c:\DocumentA.docx”, saveOptions);
doc2.save(“c:\DocumentB.docx”, saveOptions);


This is the code to create the compared document.
Also please note that even though the two source documents use the EXACT same fonts, the compare process is changing the font and marking it as a revision which makes the resulting document unusable.

Locale.setDefault(new Locale(“en”, “US”));
Document docA = new Document(“c:\DocumentA.docx”);
Document docB = new Document(“c:\DocumentB.docx”);

docA.compare(docB, “Administrator”, new Date());

System.out.println(“Documents compared”);

if (docA.getRevisions().getCount() == 0) {
System.out.println(“Documents are equal”);
} else {
System.out.println(“Documents are NOT equal”);
System.out.println("Revisions : " + docA.getRevisions().getCount());

Hi Paul,

Thanks for sharing the detail. Please note that Aspose.Words mimics the same behavior as MS Word does. If you compare "DocumentA.docx" and "DocumentB.docx" using MS Word, you will get the output with approximately same size.

The issue seems to be related to Aspose.Pdf APIs. I am moving this thread to Aspose.Pdf forum. My colleagues from Aspose.Pdf team will investigate this issue and reply you soon.

Hi Paul,

Thanks for sharing the source documents and code. I have tested your scenario with shared document using Aspose.Pdf for Java 11.7.0 and managed to observe the reported file size growth issue. For further investigation, I have logged an issue in our issue tracking system as PDFJAVA-36058 and also linked your request to it. We will keep you updated via this thread regarding the issue status.

We are sorry for the inconvenience caused.

Is there a time frame for this this fix. Our license are coming up for
renewl and we are not going to pay for software that is not working and
unusable to provide documents to our customers.

Please let me know at least the time frame as soon as possible.

Unfortunately no one in management is going to approve the renewal of software that is not working, and we are at a dead stop until these issues are addressed/fixed.
