How to increase dpi using single-file-cli?

[buran-energia]

First of all, say, there is a html page with both normal and high dpi versions of an image with the code like this:
src="imgs/pic.png" srcset="imgs/pic.png 1x, imgs/pic@2.png 2x"

is it possible to save both versions?

If not possible, what command would I use to force it to use x2 scaling / dpi?
I downloaded the Z cli version.
docker run singlefilez "https://www.wikipedia.org" > wikipedia.html"
Works fine.
But passing browsers args here gives parsing errors.

You should be able to keep all the images by setting --remove-alternative-images=false

It's working. Thank you!
