Crop PDF

What is Crop PDF Pages?

Crop PDF Pages is a free online tool that trims the visible area of your PDF pages by adjusting the margins and crop boundaries. If your document has excessive white space, unwanted headers or footers, or borders that need to be removed, this tool lets you define the exact region to keep. It is powered by the pdf-lib JavaScript library and runs entirely in your browser. Your file is never uploaded to any server, ensuring that confidential blueprints, medical records, legal documents, and personal files remain private on your device.

When to Use Crop PDF Pages

Use this tool whenever you need to adjust the visible boundaries of your PDF pages. Typical use cases include:

• Removing large margins from a scanned document to maximize the readable content area.
• Trimming printer marks, bleed areas, or registration marks from a print-ready PDF.
• Cutting out headers and footers that contain sensitive routing or tracking information.
• Cropping a specific chart, diagram, or image area from a larger page for use in a presentation.
• Standardizing margins across pages that were scanned with inconsistent borders.

How It Works

Upload your PDF by dragging it into the drop zone or selecting it via the file picker. The tool displays your pages and provides controls to set the crop margins in points or millimeters for each side (top, bottom, left, right). Adjust the values until the visible area matches what you need. Click apply, and pdf-lib modifies the crop box of each page directly within your browser, then generates the cropped PDF for download. The process is entirely client-side, so it works offline once loaded, requires no account creation, applies no watermark, and is completely free.
