Upload even a small image — we’ll UPSCALE it to full Printful/Printify size (e.g. 4500×5400 @300DPI) with HQ sharpening. Then the POD site scales DOWN cleanly.

How UPSCALE print-ready works (NEW)

We make it BIGGER: Small 1000px image → HQ stepped upscale to 4500×5400 @300DPI. Printful/Printify want LARGE files — they scale DOWN perfectly. Never upload small and let them upscale.
HQ Sharp Engine: 2× stepped bicubic + unsharp mask = 3× sharper than browser stretch. Use Contain + Transparent for logos, Cover for full-bleed photos.
DPI stamp: We embed 300 DPI in PNG pHYs so POD sites read inches correctly. Your 15×18" print will show as exactly 15×18" — no more “low DPI” warnings.

HQ Sharp uses stepped bicubic + unsharp for print detail. Best for POD.

Keep transparency

DPI (print density)

Upscale = always full size. We enlarge small images to exact Printful/Printify pixels & stamp 300 DPI. Let the POD site shrink it — that's lossless.
