The help for `quarto render` mentions that extra arguments can be given to forward to pandoc. 

And for `quarto preview` it says

> You can also include arbitrary command line arguments to be forwarded to quarto render.

This made me hope the following would work:

```
quarto preview --default-image-extension=svg
```

but it says `Error: Unknown option "--default-image-extension"`.

For `quarto render` I get the same error, but I can get it to work with e.g. `quarto render --to html --default-image-extension=svg`. I couldn't find a workaround to make it work for `quarto preview`.

(Thanks for this tool, it is truly awesome)

Extra arguments are not always passed to pandoc
