Upscayl lets you enlarge and enhance low-resolution images using advanced AI algorithms. Enlarge images without losing quality, it’s almost like magic! 🎩🪄 Upscayl is a cross-platform application built with the Linux-first philosophy. This means that Linux users receive pre-release builds earlier but Upscayl itself is available on all major desktop operating systems :)
now look what this baby can do …
Huh? A sparkly fart in the sky? 🧐
Holy fuck, a Supernova! Cosmic spectacle of incomprehensible dimensions! 🤯
I wanted to implement the pics into the post via
But it was not working for the upscayl version, sorry.
And not that everything is a competition, but in my testing the results of upscayl always look a bit better than the ones from this web based non foss upscaler.
have you tried it against waifu2x ?
The tool Upscayl uses, RealESRGAN, is superior to waifu2x - waifu2x is really showing its age at this point. waifu2x is good if you want an upscale that basically retains the same level of fidelity while increasing the resolution (i.e., usually it’s blurry). Newer upscalers try to clean up the lines and make it look like it’s an original copy.
Edit: Just for fun, here’s some tests via downscaling a picture then re-upscaling it:
Original Picture
Original Picture (downscaled)
RealESRGAN - Normal Mode
RealESRGAN - Anime Mode
waifu2x
There are also other models available to test with beyond the stock RealESRGAN ones (I’m not sure if Upscayl can use them but they’re available for CLI use). I recommend using chaiNNer - e.g. you can use a setup like this
A couple extra models:
UltraMix - Balanced
escale (probably the best for this picture)
I use Upscayl professionally and can confirm it beats out every proprietary alternative
How is it vs. Topaz Gigapixel AI or Photo AI?
