浏览器内运行这个工具能做什么
Crop all pages or a selected page range by adjusting PDF crop boxes locally. The operation is reversible in some PDF editors because it hides content outside the crop box rather than erasing drawing commands.
Margins are entered in PDF points, where 72 points equals one inch.
这个工具可以完成什么
Apply 24 points to all four sides of every page.

常见问题
Does cropping permanently delete hidden content?
Not necessarily. This tool changes each target page's crop box; content outside it can remain in the PDF data.
What unit is used?
PDF points. 72 points equals one inch, or about 28.35 points per centimeter.
Can pages have different sizes?
Yes, but the same margins are applied to every selected page. Review mixed-size documents closely.
