Question: Google Slides adds an annoying amount of compression on my imported images. I want to avoid compression so I want to upload my schematics in a vector format. I can basically export to any vector format possible.

How do I do this in Google Slides?

Answer: 
This method works flawlessly for me.

1. Upload your images/icons to Google Drive
2. Open it with CloudConvert

	* Choose export format : vector / emf.
	* Make sure that you have the checkbox to save the converted file to your Google Drive

3. Open emf file with Google Drawing
4. Copy/paste SVG icon into your Slides.

	* you can modify the colors as you wish, add or remove shapes

As of Apr 4th 2020, I just found an easier offline solution for this issue, especially if you have the shape already in PowerPoint.

1. Just copy the shape(s) to a new PowerPoint presentation and save it as a .ppt file.
2. Upload it to Drive. The uploaded file will open in Slides and the shape(s) will maintain their vector properties.
3. Copy the shapes from the new Slides document into the one you were working on.
