Is the upscaler really free?
Yes. The 4x upscaler runs in your browser with no signup, no watermark and no limit on how many images you process.
The free tool is free without conditions: 4x upscaling, no account, no watermark, no credits and no daily cap. The neural network runs on your own device, so serving it costs almost nothing and there is nothing to meter.
Two optional things sit beside it. A free account keeps your finished upscales in a library. Pro adds batches, Cloud HD (our best model, up to 8x), and video, which run in the cloud and use credits; the free tool does not change when you use it.
