Does this upload my image?

No. The browser reads the image dimensions locally and uses a temporary local preview. The image is not sent to Print Prep Lab.

Why is effective PPI more useful than the DPI label?

Effective PPI uses the real pixel count and final physical print size. A metadata label can say 300 while the file still has too few pixels for a large print.

Does a green result guarantee the final print?

No calculator can guarantee a specific printer, paper or process. A green result means the file meets the selected pixel-density target; confirm production requirements with the print provider.

Is Your Image Ready to Print?

Upload an image and check effective PPI, maximum print sizes, crop loss, bleed canvas and safe area without sending the file anywhere.

Quick answer

A print-ready image has enough real pixels for the final physical size, after any crop. This checker reads those pixels locally, calculates effective PPI and shows realistic maximum sizes at 150, 240 and 300 PPI.

effective PPI = remaining pixels ÷ final printed inches

How to use it

A result you can reproduce.

Choose the final image file or enter its pixel dimensions.
Select the physical print size and orientation.
Compare effective PPI, crop and bleed results with your printer's specification.

Every result is calculated in the page from the displayed inputs. Your printer's written production specification remains the final authority.

Worked example

See the numbers in context.

A 3600 × 2400 px image can print 12 × 8 inches at 300 PPI, 15 × 10 inches at 240 PPI or 24 × 16 inches at 150 PPI before cropping.
