Crop PDF Online (100% Free & Private)
Free crop pdf that runs in your browser. No sign-up, no install.
PDF Margin & White Space Cropper
Trims excess margins without re-encoding text or vector objects. Ensures crisp vector printing and smaller screen display areas.
What this tool does and who it is for
Crop PDF trims the same amount off all four edges of every page. You drag one slider from 10 to 100 points, which is about 0.14 to 1.39 inches, and download the cropped copy. It is handy for shaving off scanner borders or wide white margins.
The tool sets each page's crop box inset by that value on every side, with a minimum of 100 points left for width and height. The content outside the box is hidden from view in most viewers, not deleted from the file.
There is no preview and no way to crop sides separately, so open the result before you rely on it.
Official Formula / Technical Standard
Real-World Worked Scenario
Select your PDF documents, apply the desired operation, and save the updated file directly to your local storage.
When people use it
Remove scanner shadow around the edges
A thin dark border from a flatbed scan can disappear with a small even trim.
Tighten margins for reading on a phone
Cut generous white borders from a report so text appears larger on a small screen.
Prepare pages for printing
Trim off crop marks or a stray header strip when it sits within an inch of the edge.
Notes for US users
- The readout shows points and inches. 72 points make one inch, so the default of 36 is half an inch, which is a common US margin size.
- Letter pages are 612 x 792 points. A 36-point crop on each side leaves 540 x 720, so the page size shown by a viewer will change.
- If a form or filing has to keep standard page dimensions, cropping may cause rejection. Check the receiving system's requirements.
Limits and what to double-check
- •Same amount on all four sides only. No separate top, bottom, left or right values and no selection of specific pages.
- •The cropped-away content is still inside the file in many cases, so do not use this to hide sensitive information. Use a proper redaction tool for that.
- •Some viewers and printers ignore the crop box and show the full page.

Frequently Asked Questions
How does the Crop PDF work?▼
The Crop PDF runs 100% inside your web browser using modern client-side JavaScript. It performs calculations, conversions, and document processing locally on your device without sending any data to external servers.
Is this crop pdf completely free to use?▼
Yes. This tool is completely free with no usage limits, no subscriptions, and no registration required.
Is my data private when using the Crop PDF?▼
Yes. Because all operations execute locally on your computer or phone, your inputs, documents, and data never leave your browser.
Does cropping really remove the outer content?▼
Not necessarily. It sets a visible area, and most viewers show only that. The hidden part may still exist in the file and can sometimes be recovered with other software. Never rely on cropping to remove private details.
How much should I crop?▼
Start small. 20 to 36 points removes most scanner edges without cutting text. Large values on a page with tight margins will chop words. Check the first and last pages of the output, since they often have content near the edges.
Why does the page look the same in my print preview?▼
Some print drivers and older viewers use the original media size rather than the crop box. Open the file in a current browser or reader to check it, and if printing still ignores it, print the document to a new PDF first.
Can I crop just the bottom to remove a footer?▼
No. The slider trims all four sides equally. To remove only a footer, use a PDF editor that supports custom crop boxes, or cover it with a different tool. Bear in mind the same top, left and right trim will also apply here.
