Quick answer

Resize image for A4 image at 300 DPI directly in your browser. Upload an image, use the prefilled settings, process it locally, and download the result.

How it works

Sharp prints need enough pixels to hold detail at 300 DPI. For A4 image at 300 DPI that works out to 2480 × 3508 pixels, which this page applies automatically. Sizing correctly before you print avoids the soft, pixelated look you get when a small image is stretched across the page.

  1. Upload your image.
  2. Use the A4 image at 300 DPI preset at 2480 × 3508 pixels.
  3. Process and inspect the preview.
  4. Download the print-ready image.

Tips for the best result

  • Start from a source at least 2480 × 3508 pixels — print sharpness comes from real detail, and upscaling a small photo will not add it.
  • Use light compression for prints; heavy JPG compression introduces artifacts that are very visible on paper.
  • Confirm the exact pixel and DPI requirements with your print service or application portal before submitting.
