This app can scale and/or denoise images using various advanced on-device AI algorithms. Note that this app is not affiliated with the original waifu2x project. Privacy is one of the top priorities of this app. Your files will never leave your device to be processed. Additionally, we don't collect any personal information because there are no ADs even if you only use free models. Therefore, if you encounter any problems, please send us a feedback email or create a GitHub issue so that we can work together to fix them.
