waifu2x_snowshell VS realsr-ncnn-vulkan

hope this is good enough you can use waifu2x snowshell if you wanna do it yourself and try other settings.

It's literally just an AI. You just drag and drop it. I use waifu2x_snowshell because it's the most user friendly.

If you have a PC, you can download a wrapper for waifu2x like this one that lets you upscale without having to rely on a website.

And, to clarify I used Waifu 2x Snowshell with the waifu2x-ncnn-vulkan converter.

Try waifu2x... this is what I've been using and works mostly fine with even non-anime stuff. It can take advantage of CUDA for the image processing and if you are looking for a simpler way (with OpenCL support) there's a fork called Waifu2x_Snowshell it can upscale images to any limit you want locally on your machine.

Unless you have a good gpu or patience (to use your CPU). You can run it directly on a computer WHICH doesn't have a size or file limit. There are many forks like this one. Just select your setting and drag and drop :D there's also a similar version for iPhones but I can't recall the name...

There are AI upscaling tools that can increase the resolution of images at a decent quality, such as waifu2x and RealSR. I used the latter and made you 4x upscales of your photos, uploaded here:

As /u/EuphoricPenguin22 said you can use AI upscale tools to upscale your image, but I went ahead and did that for you. 😃 I used RealSR to make a 4x copy of the original, then used waifu2x to make a 8x copy from the 4x copy. Both uploaded here:
