2. Export to PDF and check the file size.
3. Export to SVG and check the file size.

please create different bugs for different problems with PPTX->PDF and PPTX->SVG
Comment 6 Ofir 2018-10-28 22:57:44 UTC
I assumed the SVG and PDF are related because both are vector formats.
Please ignore the SVG for now and let's focus on the PDF.

When I open the PDF exported from Impress in Inkscape I can see many small rectangles. The PDF exported from PowerPoint has a single element.
