Frequently asked
Will resizing distort my pages? +
Not in Fit mode. Your content scales evenly and centers on the page, so nothing gets stretched. Pick Stretch only when you want the content to fill the new page exactly, even if that warps the proportions.
Does it keep landscape pages landscape? +
Yes. If a source page is wider than it is tall, the target size rotates to match it. A landscape page stays landscape.
What size is A4 in points? +
A4 is 595.28 × 841.89 pt (210 × 297 mm). Letter is 612 × 792 pt, Legal 612 × 1008 pt, A3 841.89 × 1190.55 pt. It all runs in your browser.
