The best part of Stability AI’s image upscaler is that it’sfree to use for 2x image upscaling. If you want upscale images 4x to 16x, you need to subscribe to the paid plan.

SuperImage is available on Android and Windows for now, but the developer says it’s also coming to macOS and Linux very soon. So, I would say, if you have a flagship Android phone or a powerful PC, go ahead and try this tool.
