How to crop a PDF
Cropping a PDF adjusts the visible area of each page by trimming margins. This is useful when you want to remove extra white space, hide headers or footers, or focus on the main content area. Unlike compression, cropping changes what is displayed without altering the underlying content.
This free tool lets you set crop margins independently for each side: top, right, bottom, and left. Each margin is expressed as a percentage of the page dimensions, so the crop scales proportionally across pages of different sizes. The tool applies the same crop settings to every page in the document.
All processing happens locally in your browser using pdf-lib, a powerful JavaScript PDF library. Your PDF files are never uploaded to any server, ensuring complete privacy. The tool supports PDFs up to 100 MB and works with any PDF document.
Frequently asked questions
What does cropping a PDF do?
Cropping a PDF sets the visible area of each page by trimming margins. The content outside the crop area is hidden but not deleted from the file.
Are all pages cropped the same way?
Yes. The same margin percentages are applied to every page of the PDF. Each page is cropped proportionally to its own dimensions.
Can I crop only specific pages?
Currently the tool crops all pages uniformly. To crop specific pages, split the PDF first, crop the relevant parts, then merge them back.
Will cropping reduce the file size?
Cropping changes the visible area (CropBox) but does not remove content from the file. File size may decrease slightly, but the main purpose is to adjust what is visible, not to compress.
Is my PDF uploaded to a server?
No. All processing happens locally in your browser using pdf-lib. Your files never leave your device.
