Hi @aday ,
Maybe you can try the code below to control the scaling of pages in webbrowser.
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
webBrowser1.Document.Body.Style = "zoom:120%";
}
You can refer to other solutions in the link below.
Zoom in on a web page using WebBrowser .NET control
Best Regards.
