Lets you click on the extension icon or right click on an .svg file and choose Save SVG as PNG. You will be able to specify the desired width of the rendered PNG image. The image will be opened in a new tab where you can see it and right click on it to save it to disk. This only works if you have the .svg file open in its own tab, you can't click on a svg file that's embedded in a page, you would first have to right click on it, choose "Open image in new tab" and then go to that tab to convert it to png.
