PNG of SVG of Jitsi-logo

Hey,

I’m preparing a tutorial (in Dutch)about Jitsi.
It would be nice to have the logo in ‘good shape’.
I can download the png from the website, but that is rather small, and I can’t make it bigger without loosing quality.
Can someone give me a larger image? svg would be magnificent.

Thanks,
Stefan
