Simple Process
How PrintCheck Works
Three quick steps to ensure your physical prints never come out blurry or pixelated.
Input Target Dimensions

Upload Your Image
Select your image file. Our engine inspects metadata in memory using Pillow without saving your file to disk.

Instantly view whether your image passes, qualifies for AI upscaling, or requires a higher-resolution file.
