Frequently asked questions

Is the content scaled?

Yes. Each page is scaled to fit the new size and centred, keeping its proportions, so nothing is cut off.

What about landscape pages?

They stay landscape and use the landscape version of the size you pick.

Does it reduce quality?

No. Text and graphics stay vector-sharp; nothing is re-rendered.

Can I resize a phone scan to A4?

Yes. Odd-sized scans are scaled to fit A4 (or any size you pick), so they print cleanly.
