Prepare images for PDI

Choose your editing application for step-by-step guidance on sizing, colour space and JPEG export.

Required specification

Before you begin

  • The image must fit within 1600 pixels wide × 1200 pixels high, including portrait images.
  • Save the finished image as a high-quality JPEG.
  • Use the sRGB colour space.
  • Do not stretch, distort or crop an image simply to fill the available dimensions.
Important: 1600 × 1200 is a maximum bounding box, not a required canvas size. Smaller dimensions are accepted.
