Your photo never leaves this computer — everything happens in your browser.
JPEG, PNG, or WebP work best
What size print will you order?
Enter the size you'll order from your print service. The test file is created at 300 DPI (print quality).
How small should each version be?
Smaller versions = more variations on the sheet, but each is harder to judge. Each version keeps your photo's shape.
Which adjustments do you want to test?
Pick what you suspect looks wrong in your prints. Not sure which to choose? Hover over any option for a simple explanation of what it does and what it fixes. Based on how many you pick, you'll get layout choices below.
Labels, preview & download
Either way you also get a separate key file to keep at home, so you can match the print back to exact settings.
Load your original photo
