IMPORT OF ILLUSTRATIONS FROM EXCEL, WORD, POWERPOINT -> BAD QUALITY

Does anyone know, how to import illustrations from Microsoft products into Scrivener without loosing quality.

What I usally do is, save the illustration with a right click as a PDF and then import it into another program. That leads to the best quality. In Scrivener that does not work, the quality dramatically drops.

The only workaround compiling everything to word and manually set up everything. That usually cost me hours!!

In case there is no solution, I have to leave Scrivener…

THANKS A LOT!
