For print shops, print-on-demand & photographers
Customers send small, soft or noisy files. Upscale them to the pixels a poster, canvas or T-shirt needs, remove noise and blur and correct color, so you can say yes to the order instead of asking for a better file.

Print size × DPI = pixels. 300 DPI is the usual target for photos viewed up close, 150 DPI is enough for posters and canvas seen from a distance.
| Print size | 150 DPI | 300 DPI |
|---|---|---|
| 4 × 6 in (10 × 15 cm) | 600 × 900 px | 1,200 × 1,800 px |
| 8 × 10 in | 1,200 × 1,500 px | 2,400 × 3,000 px |
| A4 (210 × 297 mm) | 1,241 × 1,754 px | 2,481 × 3,508 px |
| A3 (297 × 420 mm) | 1,754 × 2,481 px | 3,508 × 4,961 px |
| A2 (420 × 594 mm) | 2,481 × 3,508 px | 4,961 × 7,016 px |
| 18 × 24 in poster | 2,700 × 3,600 px | 5,400 × 7,200 px |
| 24 × 36 in poster | 3,600 × 5,400 px | 7,200 × 10,800 px |
A 12 MP phone photo is about 4,000 × 3,000 px: enough for A4 at 300 DPI. A 24 × 36 in poster at 300 DPI needs 10,800 × 7,200 px, about 2.7× more on the long side.
What usually stands between a customer's file and a sharp print, fixed automatically.
Enter the print size and DPI and the Upscale tool works out the scale, or pick 2× to 16× yourself. AI adds real detail instead of stretching pixels, so edges and textures stay sharp on large formats.
Phone photos, screenshots and images saved from the web carry grain, JPEG blocks and soft focus that a print makes obvious. Clean them up before you enlarge, in the same request.
Dark, flat or color-cast photos print even darker. Fix exposure, contrast and white balance automatically so prints come out the way the customer remembers the moment.

Set the size and DPI or a scale in Upscale. If the file is also noisy, blurry or dark, use AI Enhancer PRO, which fixes that and upscales in one go.

Multiply the print size in inches by the DPI. For a sharp photo print at 300 DPI, an 8 × 10 in print needs 2,400 × 3,000 px. Posters and canvas viewed from a distance look good at 150 DPI, so an 18 × 24 in poster needs 2,700 × 3,600 px.
In most cases, yes. AI upscaling adds detail rather than just stretching pixels, so edges and textures stay sharp. Results depend on the source: a clean small file upscales very well, a heavily compressed or very blurry one improves but cannot gain detail it never had.
Open the Upscale tool, choose Target size, then Print size, and enter the print's width and height and 300 DPI. The tool works out the scale and shows the result's size before you run it.
Up to 16× in the account Upscale tool. The largest output depends on your plan; see the pricing page for the resolution each plan allows.
Yes. Upload up to 50 files at once in AI Enhancer PRO with the same settings, or call the REST API from your shop so every uploaded design is upscaled before it goes to print.
Common photo formats such as JPG, PNG, WEBP and HEIC. Through the API you can also send TIFF and camera RAW files.
