What is the difference between CropBox and Flatten modes?

CropBox hides content outside the crop area but keeps it in the file (reversible). Flatten mode permanently removes cropped content, producing a smaller file.

Can I crop individual pages differently?

Yes — enable "Custom per-page" mode to set different crop margins for each page.

What is Auto-crop whitespace?

It automatically detects white borders around the page content and removes them, like a document scanner trim.

Can I enter exact crop values?

Yes — use Numeric Input mode to enter precise top, right, bottom, and left margins in mm, inches, or PDF points.
