Aspose.Pdf.dll takes a long time to convert PDF files to other format files

Hi Aspose team,

We try to use Aspose.Pdf.dll v18.6 to convert pdf to other format files: .DOC, .XLS, .PPT, .DOCX, .XLSX, .PPTX, .SVG, .EPUB, .XPS and .XML.And we found a lot of problems:

  1. When we try to convert a .pdf file(>1MB) to an office file, only a 0kb office file will be generated, and the conversion time will take hours
  2. Convert pdf file to xls file, when we open xls file, it will prompt the file is corrupted and it will show incorrect typography.
  3. Pictures will be deleted when converted to epub, xps and excel files
  4. There will be a large blank when converted to html file. Compared with the previous html, the scroll bar cannot scroll.
  5. Crash when converting to xml file

Please have a check. Thanks.

Here’s the demo code and test files.
FYI, we get the code here


Thank you for contacting support.

Please always create separate topics for separate issues, for future references, as it helps us addressing your concerns efficiently. We have been able to notice the problem with PDF to DOCX and XLS conversion and the tickets with IDs PDFNET-47374 and PDFNET-47375 have been logged respectively.

Moreover, we have not been able to reproduce third problem like attached XPS document looks fine. Issue3_epubTopdf.pdf_19.11.zip

Generated HTML file looks fine as well. issue4.zip

For XML conversion, it needs the PDF document to be a tagged document so the exception is thrown.

Please ensure using Aspose.PDF for .NET 19.11 and share some screenshots as well if problems persists.
