Pixupscale Reviews 

Same as other mentioned below. Stay away from this website. Will charge you 50 cent only for a 3 day trial period of 3 days and wont let you know at that point that they will charge you 40 Euros after the 3 day trial period ends and you do not cancel your subscription and I have seen many other websites like this. Careful.

it even made the picture worse and I had to pay for the trial version... very bad experience

One star, and honestly I'd give zero if I could. The results are absolute garbage, and the business model is incredibly shady. They advertise a "50 cent trial," but buried in the fine print is the fact that they'll charge you 40 euros once the trial period ends. For that kind of money, you could just get a proper tool with a real monthly subscription instead. Stay away.

Poor quality. It isn't capable of upscaling and exporting hi-res images. I should've read the reviews before trying it.

First, the quality of this tool is really not up to the task : it does not upscale correctly at all.
Second, they clearly try to trap you into their short trial, and make it very unclear on their website the rules of cancelation and found a pseudo loophole not to apply the 14 day refund policy.
Worse : they tell you that if you have tried the tool once, you cannot be refunded for the automatic renewal.
As soon as you start paying 40€ / month for the normal subscription, they will not give you a refund. Doesn’t matter if you write them an email same day and you never used the service in any way.

Unfortunately, they bait you into their trial, and make it very unclear on their website where to cancel it.
