This app that can upscale anime-styled images, gifs, and videos using waifu2x or Real-ESRGAN Anime.
The photo upscaler feature uses Real-ESRGAN's portable executable file (Real-ESRGAN-ncnn-vulkan) to upscale images with extremely high quality.
Note: Upscaling videos and gifs will take a very long time without a high-end graphics card
