Short answer: this page reports facts about your file and does simple arithmetic. It does not set a resolution rule for your order. Ask the factory to confirm what it needs for your size.
How to use this in 3 steps
- Drop an image file on the box, or choose one.
- Optionally type a pixels-per-inch figure and a size in inches or cm.
- Read the pixels, megapixels, shape and the arithmetic.
Your file stays in your browser. The page reads only its pixel width and height; nothing is uploaded.

What the numbers mean
Pixels are the dots in the file. Megapixels are width times height divided by one million. Pixels per inch (ppi) is the pixel count divided by the print size in inches, so a file shows a different ppi at every size. Printers and guides give different figures, so the ppi box is yours to fill and carries no ArtzFolio promise. Read the canvas print resolution and colour guide for what trusted sources say, and the artwork requirements for what to send.
