Waifu2x is a platform that allows you to double the size of any image without loosing quality. Depending on the detail of the original image, you will be getting a greater or lower quality, but all the proccesed images will look great.
Yes, completely free. All the images that you want to scale, at any time, at any place, completely free. Even though, we have to pay for the servers so, if you want to help us, remember that we have a Patreon where you can do it.
Yes, we have a mobile version of Waifu2x. It comes in two versions, a free version and a premium version. The two apps are the same in terms of funcionaluty, but the free version has ads to help us maintain the servers. The premium version comes with no ads and the new updates will be publised previously on this version.
All the images proccessed images are stores in our servers until you download them. When a image gets proccesed and downloaded, it will be removed from our servers. If you want to get the same image again, you will have to upload it again.
