About Crop PDF
How PDF Cropping Works
Cropping a PDF adjusts the visible area of each page by trimming margins from any side. Content outside the crop region is hidden — the original data stays in the file, but viewers only display the cropped area.
OxygenPDF sets both the CropBox and MediaBox on every page. You specify margins in PDF points (1 point ≈ 0.35 mm) for each side: top, right, bottom, and left. The preview shows the effect before you apply. Everything runs in your browser.
When You Need to Crop a PDF
PDFs often come with more whitespace than you need. Cropping trims the excess so content fills the page.
Print Optimization
Remove wide margins so content prints larger on the page. Useful for slides, diagrams, and technical drawings.
Mobile Reading
Big margins waste screen space on phones and tablets. Crop them and the text fills the display.
Presentation Materials
Exported slides often have excessive whitespace. Crop to the content area for cleaner handouts.
Standardize Margins
Documents from different sources have inconsistent margins. Crop them all to the same dimensions for a uniform look.
How It Compares
PDF cropping is straightforward. The differences come down to whether you can set independent margins per side and whether your file gets uploaded.

Built for Files You Can’t Share
Cropping happens entirely in your browser. Your PDF isn’t uploaded anywhere. The cropped output downloads to your machine. Close the tab and it’s gone.
