  • Photo labs may add bleed, crop or color corrections.
  • No image is uploaded for the calculation.

4x6 photo pixel calculation notes

A 4 x 6 inch photo converts cleanly from inches to pixels by multiplying each side by DPI.

The result helps you prepare photo exports before sending them to a lab or printer.

Common use cases

  • Planning 4x6 photo prints
  • Checking whether a photo has enough pixels
  • Resizing images before printing

Photo print notes

  • 4 x 6 at 300 DPI is 1200 x 1800 pixels.
  • Some labs crop slightly, so keep important content away from edges.
  • Use JPG for ordinary photo prints unless the lab asks for another format.

Original test sample

  • Set 4 x 6 to 300 DPI and confirm 1200 x 1800 pixels.
  • Try 600 DPI to see the higher-resolution archive target.

Frequently asked questions

Are my images uploaded?

No. ImgShrink processes selected images in your browser and does not upload them to a server.

Which DPI should I use?

300 DPI is a common high-quality print target, 150 DPI can work for general print, and 72 or 96 DPI is mainly screen-oriented.

Is this a final print or document approval check?

No. The calculator gives pixel, DPI and physical-size math. Printers, passport offices and upload portals may apply extra rules.

Source and compatibility notes

DPI and print-size results use standard pixel-to-physical-size formulas. Document-photo presets are reference sizes, not a substitute for official submission rules.
