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.
Use page-box cropping to remove scanner borders or focus a handout on its useful region.
Margins are entered in PDF points, where 72 points equals one inch.
这个工具适合解决什么问题
Apply 24 points to all four sides of every page.
依赖结果前需要检查什么
- Cropping hides out-of-box content and is not a secure redaction method.
- One margin set is applied to all selected pages, including mixed-size pages.
如果还需要校验、转换或复用结果，可以继续打开相近的浏览器本地工具。
如何使用
01使用场景
Hide dark or uneven borders around a scanned packet.
Crop excess whitespace from PDF slides before placing them in another document.
常见问题
02Does 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.
