About this option

Posters, architectural drawings and detailed infographics need more pixels than a screen-sized export gives. This preset renders pages at the Print setting — three times screen resolution — as lossless PNG files, so you can zoom, crop or print without visible blur.

When to use it

  • Preparing a poster or large drawing for print
  • Zooming into small text or fine lines in a diagram
  • Cropping a detail out of a page without it turning soft

How to use it

  1. 1Drop the PDF — PNG at print resolution is already selected
  2. 2Limit the pages (high-resolution pages are big, so only pick what you need)
  3. 3Click Convert and let the larger pages render
  4. 4Download the PNG files

Frequently asked questions

How large is print resolution?

Three times screen resolution, around 2700 pixels across for a standard page, which prints sharply at A4 size.

Why is it slower?

Each page has about four times as many pixels as a screen-sized export, so it takes longer and the files are larger.

Is there a limit on very large pages?

Your browser has a maximum canvas size. If a page is huge it is rendered at the largest size the device can handle.
