What does Crop PDF do?

It trims the visible area of each page by setting margins. You specify how many points to remove from each side. The content outside the crop area is hidden.

Is my PDF uploaded to a server?

No. Cropping runs in your browser. Your file stays on your device.

Does cropping permanently delete content?

The original content remains in the file structure. Cropping adjusts the crop and media boxes that determine the visible area. Some viewers may still be able to access the original bounds.

Can I set different margins for each side?

Yes. Top, right, bottom, and left margins are independently adjustable.

What units are the margins in?

PDF points. One point is approximately 0.35 mm or 1/72 of an inch.

Does it work with password-protected PDFs?

Yes. Enter the password when prompted. Decryption happens in your browser.

Can I crop multiple PDFs at once?

Yes. Batch mode applies the same margins to all files.

Can I crop PDFs on my phone?

Yes. The mobile layout puts margin controls in a bottom sheet.

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.
