This method is much faster and much easier.

Though it didn't work for me.
Closest alternative to this would be to just scale up the textures a bunch.
Since this doesn't work. (For me, at least.)

Not sure why it didn't work for you? What format did you try to enlarge?
Upscaling an image regularly doesn't do much because and detailed textures will be rather blurry. 
Doing this it upscales it, sharpens and smooths out the image making the details of the smaller image stay intact.

I know what upscale filtering is.
It's also a system used in PSP games.
Just makes textures smoother and more clear.
Like in the older Project DIVA 2nd and Extend games.

I'm sure it's just the website, thought it could be my browser too.
I went to it, followed what you said, it's pretty basic.
Uploaded an image of the same format. (256x256 .png from Pokemon X & Y)
Clicked "Convert", it opens a new tab, loads for 5 minutes and then brings up a "cannot connect" page.

I'm trying it again and I can get it to work now but I notice no difference in the image.
Trying again...

Okay, it seems I got it to work.
It wasn't working before for whatever reason.
Sorry~
