Focus on what matters. Our Crop PDF tool lets you trim margins, remove headers and footers, or cut down page sizes to fit specific printing requirements.
What is PDF Cropping?
Cropping involves redefining the visible area of a document page. Unlike resizing, which shrinks the entire content, cropping cuts away the outer edges, leaving only the selected rectangular area visible.
How it Works
You draw a selection box on a preview of your document. We then calculate the coordinates and apply a "CropBox" definition to every page in the PDF file, effectively hiding everything outside your selection.
How to Crop PDF Margins
- Upload: Select the PDF you wish to trim.
- Select: Use your mouse to draw a box around the content you want to keep.
- Adjust: Fine-tune the box size to ensure nothing important is cut off.
- Apply: Click "Crop PDF" to update all pages and download the result.
Key Features
- Visual Interface: See exactly what you are cutting with our real-time preview canvas.
- Batch Application: The crop selection is applied to every page in the document automatically.
- Non-Destructive: While the content is hidden, the underlying data remains in the file (standard PDF behavior), allowing for future adjustments if needed.

Frequently Asked Questions
Does cropping delete the data?
Standard PDF cropping only "hides" the data outside the box. To permanently remove it, you would need a "Sanitize" or "Redact" tool.
Can I crop different pages differently?
This tool applies a uniform crop to the whole document. For individual cropping, split the PDF first.
Why is the file size the same?
Since the content outside the crop box is hidden rather than deleted, the file size often remains unchanged.
