I have a spreadsheet that I use as a template for invoices. It was created with OpenOffice many years ago. Since then, I used the export to pdf function to create a pdf version of my 1 page invoices. The file size of the generated pdfs was an average of 50kb.
I recently installed LibreOffice. When I open the same ods file and do the exact same export to pdf, the file size is around 250kb!! Five times bigger!! There are no images in the file and I played with all the options in the export to pdf dialog with no avail (actually some options make the file even bigger).
Any idea what could be making these pdfs so big now? How can I make the pdf file size more efficient?
