Frequently asked questions

What does resizing to A4 do to landscape pages?

Landscape pages are resized to fit A4 dimensions. The content is scaled proportionally, so nothing is cropped.

Can I resize and compress in the same command?

Yes. Ask PDF supports combined commands like 'make every page A4 and compress below 5 MB'.
