Crop PDF
Adjust the visible margins of your pages to trim white borders or unwanted areas. Processed in your browser, with no upload.
The Crop PDF tool adjusts the visible area of pages by applying a uniform margin in points. Processing happens in your browser.
You set a margin in points (1 point = 1/72 inch) and the tool applies the uniform crop to all pages, adjusting each page's CropBox.
Cropping uses pdf-lib to change the viewing box of each page. Content outside the new area stops appearing, without manual editing.
It is useful for removing white borders from scans, adjusting document margins, or standardizing the usable area of a material.
When to use it
- Removing white borders from a scanned document.

Frequently asked questions
What does margin in points mean?
It is the distance cropped from each edge. One point equals 1/72 inch, applied uniformly to all pages.
Is the original content erased?
Content outside the new area stops being displayed, but cropping only changes the page's viewing box.
Can I crop just one page?
No. The tool applies the same uniform margin to every page of the document.
