Good to know
What does it do to my design?+
An AI model rebuilds the design at 2× or 4× the size, so edges and lines come out sharper instead of soft and blocky. It works best on illustrations, lettering and logos.
Does it keep the transparent background?+
Yes. Transparent PNGs stay transparent, and the edges of the design are kept crisp.
What is 4500 × 5400 px?+
The front print size Printify and Printful recommend for tees, at 300 DPI. Tick “Fit to print size” and the result is placed on a canvas of exactly that size, ready to upload.
Can it fix a very small or blurry image?+
It can make it noticeably sharper, but it can't invent detail that isn't there. For print, start from the largest file you have.
Are my designs uploaded?+
No. The AI runs on your device; the first run downloads a small model (about 3 MB). Large designs can take up to a minute.
