About PrintCheck

PrintCheck answers one question before you pay for a print: will this image look sharp at the size I want?

Why it exists

Blurry prints are one of the most common and most avoidable printing problems. Photos saved from social media, AI art at its default size and designs exported too small all look fine on a screen and disappointing on paper. Most people only find out when the print arrives.

Working out whether a file is big enough means juggling pixels, inches, millimetres and DPI. PrintCheck does that in a few seconds: upload an image, choose a print size and it tells you whether the file will print sharp, whether AI upscaling could rescue it, or whether it is simply too small.

How it works

• It reads your image’s pixel width and height and compares them with the pixels needed for your print size and resolution.
• If the image is short of pixels but within 4×, it suggests an AI upscale factor. Beyond that, it suggests a smaller size.
• It shows the largest size the image can print at, in millimetres and inches.

The guides explain the ideas behind it in plain English, from DPI vs PPI to when AI upscaling works.

Your images stay yours

Your image is only used to read its size and format, and is deleted as soon as the check is finished. It is never stored, looked at or shared, and there are no accounts. Anonymous statistics about checks (such as pixel size and result, never the file name) help improve the tool. Full details are in the privacy policy.

How it stays free

PrintCheck is free to use with no sign-up. The costs of running it are covered by:

• Recommending print and upscaling services through affiliate links. If you buy through them, I may earn a small commission at no extra cost to you. I only recommend services that fit what the tool does.
• Readers who choose to buy me a coffee.
• In the future, possibly advertising. Ads will never affect what the checker tells you.

Who runs it

PrintCheck is built and run by Chris Bezuidenhout, an independent developer based in the EU. It is a small, independent project, not part of a print company, so its results are not tied to selling you prints.
