Why AI images need upscaling before print
Most AI models make pictures of about 1024 × 1024 pixels. That is plenty for a screen and far too little for fabric: at the 300 pixels per inch a printer wants, it covers 3.4 inches. Stretched over a shirt front it prints soft and blocky.
An AI upscaler does not stretch the pixels. It redraws the picture at the larger size, keeping edges crisp and filling in detail. Four times bigger turns 1024 pixels into 4096, enough for a 13.7 inch print at full quality. The print size calculator tells you how many pixels your product needs.
Why this one costs credits
The other tools here run on your own device, so they cost nothing to offer. Upscaling at this quality needs large models on rented graphics cards, and every run is paid for. It is charged in credits, at the price shown on the button before you press it. The pricing page shows what credits cost and what a new account starts with.
An upscale you have paid for is kept in your account: the same image with the same settings is not charged a second time.

Questions people ask
Is the upscaler free?
No. It runs on paid AI models, so it costs credits. The price depends on the size of the image and the model you choose, and you see it before anything is charged. The pricing page shows what credits cost and what a new account starts with. The other tools here are free.
How much bigger can an image be made?
Two or four times on each side. An image can go in at up to 4096 pixels on its long side and come out at up to 8192. A 1024 × 1024 image made four times bigger is 4096 × 4096 pixels, which prints sharp at 13.7 inches.
Does it keep a transparent background?
Yes. The shape of the design is cut back out of the enlarged picture, so a transparent PNG comes back transparent.
Is my image uploaded?
Yes, for this tool. The image is sent to SlapMake and to fal.ai, the service that runs the AI models. The result is kept in your account, so asking for the same image again with the same settings is not charged twice.
Which of the three ways should I choose?
Faithful keeps the picture exactly as it is, only sharper: the safe choice for logos, text and flat artwork. Restore also cleans up blur and noise. Enhance adds fine detail, which suits painterly and photographic images, but small things in the picture may change.
