imgproxy VS waifu2x

We use imgproxy which does 2->4 and all you need to do is change the URL on your site. Source: 6 months ago

You should also be using a variety of formats. Unless you need support for old browsers and transparency in the same image, don't use PNG. Stick with jpg, webp and avif. You can setup something like imgproxy to automatically resize and change format of images, or even fit into the space requirements you set. Source: about 1 year ago

If you look for something universal, you can try API for image optimization (e.g. imgproxy). However, the mechanism is different from build-time optimization. Source: about 1 year ago

Now signup for Vultr and make a $5 instance and put imgproxy on it. Setup a subdomain for images in Cloudflare and point it to the imgproxy IP. Source: about 1 year ago

If you need optimization done en masse on the website, I would recommend https://imgproxy.net/. Source: about 1 year ago

In an effort to restore them as much as I could, I used a combination of waifu2x ("Single-Image Super-Resolution for Anime-Style Art using Deep Convolutional Neural Networks"), Clip Studio Paint resize/cleanup tools, and manual cleanup done by hand. Unfortunately, the red text on the title page was a lost cause. If anyone can decipher solid red rectangles please contact me lol. Source: about 1 year ago

Maybe this would help. There's also an app version of it. Source: about 1 year ago

I would recommend putting it through an upscaler beforehand, it seems a bit small. Source: over 1 year ago

Http://waifu2x.udp.jp/index.html found this image upscaler from https://www.reddit.com/r/FireEmblemHeroes/comments/a51f0k/i_turned_yusuke_kozakis_artwork_into_a_high/?st=JPIZKYIB&sh=f12f76fe a while ago, perhaps that would be the closest if IS doesn't release anything. Source: over 1 year ago

You can make it bigger for print by using by using an Japanese AI image enlarging tool. Source: over 1 year ago
