Print-on-demand tool

PrintReady DPI

Image print-prep for print-on-demand uploads. It cleans up transparency, pads your image to a 4500×5400 canvas, and sets 300 DPI — so uploads stop getting rejected for size or DPI. It is downscale-only: it will not upscale or invent detail that is not in your file.

Who it’s for

Etsy and print-on-demand sellers whose designs — often AI-generated or exported at the wrong size — keep failing platform size and DPI checks.

Key features

  • Transparency cleanup — cleans alpha/transparency issues before upload.
  • 4500×5400 canvas pad — pads your image to the standard POD canvas size.
  • 300 DPI set — stamps the correct DPI so the file passes size/DPI checks.
  • Downscale-only — never upscales and never invents detail; your art stays your art.
  • Instruction guide included — prep steps with every purchase.

Disclaimer: PrintReady DPI prepares files as described — canvas size and DPI metadata. Marketplace and print-provider acceptance depends on each platform’s own rules and review, and is not guaranteed. Check your printed result; a correct DPI value does not add detail to a low-resolution source. See the full Disclaimers.
