FAQ
Frequently asked questions
What is the difference between "Fit inside" and "Stretch"?
"Fit inside" scales pages proportionally and centers them with neat margins. "Stretch" expands the content to match exact dimensions.
Does resizing re-render or blur the text?
No. Pages are embedded as native vector objects inside the new page dimensions, so text sharpness is preserved.
Can I resize mixed-orientation documents?
Yes. Each page is adapted to the target dimensions according to the fit algorithm.
