I am completing some evaluation work of Aspose.Words, and I am looking at the files it is generating when saving a word doc as a PDF.
Thanks for your request.
You see the significant difference in file size because Aspose.Words always embeds font subsets into the PDF documents. Core fonts are 14 fonts, which are supported by PDF viewers by default. These fonts can be optionally embedded or not into PDF.
Since MS Word does not embed core fonts – size of PDF it produces is significantly smaller. <?XML:NAMESPACE PREFIX = O />
We will consider adding an option to use core fonts in one of future versions of Aspose.Words. We will let you know once this option is available.
