Converting XLS document to PDF in huge size

Hi Support,

We are using Aspose.Cells for document conversion. for particular files which contains mostly images, the output document size is dramatically huge. Kindly check and lets us know what could be the reason?

input document size: 1.35MB

output PDF size: 9.02 MB

See attached sample input document

NOTE: we are converting document in PDF with PDF/1A compliance and using Aspose.Cells for .NET 7.4.2.0 release

Hi,

Thanks for your posting and using Aspose.Cells.

Please download and use the latest version: Aspose.Cells
for .NET v7.4.3.1
. It works fine.

The latest version generated the pdf of size 7MB. Below is a sample test code used to generate the output pdf.

C#


string filePath = @“F:\Shak-Data-RW\Downloads\landscape\landscape.xls”;


Workbook workbook = new Workbook(filePath);


PdfSaveOptions opts = new PdfSaveOptions();

opts.Compliance = PdfCompliance.PdfA1b;


workbook.Save(filePath + “.out.pdf”, opts);

Hi Shakeel,

Alright the size little bit decreased but its still huge as per our expectations.

Just imagine the document of size 1.38MB converted in 7.07MB almost 5-times larger even resources are also embedded in the source document.

Kindly try to improve it more.

Wahaj
