Understanding PDF Cropping

What Does It Mean to Crop a PDF?

Cropping a PDF means adjusting the visible boundary of a page to hide or remove content outside a defined area.

This is especially useful when preparing documents for printing, presentations, or sharing.

What Is the Difference Between Cropping and Trimming a PDF?
