Know the tradeoffs

  • Fitting pages can introduce margins when the source and target proportions differ.
  • Resizing cannot add detail to a low-resolution scan.

Questions about this tool

Can I change an A4 document to Letter?

Yes. Select Letter as the target paper size.

Does changing paper size make a blurry scan sharper?

No. The amount of detail still depends on the original image.
