Does responsive images compresses the images?

[FrazeColder]

Hey,

I am using the Spatie media-library and this package is awesome!

However, I am not quite sure if the function ->withResponsiveImages() generates only smaller image sizes or also smaller image sizes which are being compressed over and over again?

I am not talking about media conversions, I am talking about a normal media collection, e.g.

public function registerMediaCollections(): void
    {
        $this
            ->addMediaCollection(config('media-collection.comments.content'))
            ->useDisk('commentFiles')
            ->withResponsiveImages();
    }

I did not find any information about that in the docs. Can you please tell me if the function ->withResponsiveImages() does not only reduce the width of the image but also compresses it?

If so, how can I disable the compression or at least do not compress the images that strong?
I am asking, because in my eyes, the responsive images look way too compressed.

Kind regards
