Here is what I tried:
- Save this maths formula from Wiki as SVG
- Open the SVG in Adobe Illustrator
- Save it as PDF (File / Save as / Format PDF)
I noticed that the file size of the PDF is 60x times larger (600KB bs. 10KB). While I can accept that PDF is a somewhat bloated, proprietary format, I still cannot believe this discrepancy.
Can anyone explain to me why SVG can save the vector graphics more size-efficiently, and how I can reduce the file size of the PDF (without sacrificing any quality).
I can imagine that it has something to do with the PDF presets. But I am reluctant to change those, because I often get problems after changing presets when importing PDFs in other tools (e.g., Microsoft Office tools).
