settings for export

Hi @Iztok, I managed to get an export of your 31.4 mb pdf down to 1.5 mb (see attached) in Publisher 2.5.5 using the default PDF (digital - small size) settings with many of the vector elements still intact. I don't have the font you're using so it's substituted a standard font, but that makes me wonder if possibly the embedded font you are using might be the source of the larger file size. 

I would try changing the settings for embedded fonts to see if that helps, and I'd also suggest ensuring subset fonts is checked in case you're using large, international fonts with hundreds (or possibly thousands) of glyphs that are not actually used in your document.

Just to follow up on my font theory (above). In looking at the original 31.4 mb PDF in Acrobat Pro, it appears that all of the fonts have indeed been subsetted in the original export. I then exported another version from Acrobat Pro using the File -> Compress a PDF option and the resulting file was just under 4MB. 

Not sure what's going on here, but there's definitely some inconstencies in Publisher's output.

This was discussed about a year ago, where even converting color spaces and/or rasterizing images gave larger file size. I think Hangman tried a few variations and got bigger PDF size with optimization vs no optimization. It was logged as a bug to further investigate, but we all know how Serif works..
