How to Prepare Images for Large-Format Printing (A1–A5)

Want your A1–A5 print to look crisp? Run this checklist before you export.

1) Start with the best source

  • Use the original file (not a screenshot or social export).
  • Prefer RAW → export to PNG or high-quality JPEG.

2) Target size & PPI

  • Aim for 300 PPI if viewed up close; 150–200 PPI works for posters viewed from a distance.
  • A-series at 300 PPI (approx pixels): A3 3508×4961, A2 4961×7016, A1 7016×9933.

3) Clean before upscaling

  • Reduce noise and fix exposure/white balance.
  • Heal obvious artifacts before enlarging—they only get bigger.

4) Upscale

  • Use 2–4× upscale to hit your target pixels. If you’re short, upscale first, then downsize to the exact print size.

5) Sharpen last (lightly)

  • Apply subtle output sharpening after you reach final size.

6) Color & profile

  • Use sRGB unless your print shop asks for CMYK.
  • Avoid oversaturation—prints are less luminous than screens.

7) Export

  • PNG for graphics/flat color; JPEG (quality 90–100) for photos.
  • No watermarks or multiple compression passes.

Tip: PrintUpscale gives you a ZIP with A1–A5 sized PNGs, ready to go.
