Good to know
- Pages are scaled to fit and centered; their shape is kept, so you may see white space at the edges.
- "Like each page" keeps landscape pages landscape.
- Text stays sharp and selectable: pages are placed as vector content, not turned into pictures.
- Links and form fields of the original pages are not kept.
