How to Crop a PDF to Remove White Margins Online

Fix scanned pages and exported documents by trimming extra whitespace around the content.

Where Do These White Margins Come From?

Scanners and export settings often leave a big white border around the actual page content. This makes your document look tiny, wastes ink when printing, and can look unprofessional when you share it.

The quickest fix is to crop the PDF so only the important area of the page remains.

Crop Your PDF in a Few Clicks

Open the Crop PDF tool.
Upload your PDF and wait for the preview to load.
Drag the crop handles to select the content area you want to keep.
Apply the same crop to all pages if they share the same margins.
Download the new, margin-free PDF.

For scans, class notes, or photo-based PDFs, this simple step can make a huge difference in readability.

Best Use Cases

Scanned notebooks or textbooks with big scanner borders
ID cards and certificates with excess whitespace
Receipts and bills that sit in a small corner of the page
Forms exported with default margins that are too wide

Once cropped, you can also compress the PDF or merge it with other documents as needed.
