About the PDF Cropper
Our free online PDF cropper trims unwanted margins from your document's pages. Remove excess white space, cut off headers and footers, or fit a scanned document for printing — choose a preset trim or enter your own custom Top, Bottom, Left, and Right margins.
Unlike most online tools, cropping happens entirely inside your browser using the pdf-lib library — your document is never uploaded to a server. That means it's fast, works without an internet round-trip, and keeps your files completely private and secure.

Frequently Asked Questions
Does cropping a PDF delete the content outside the cropped area?
No. Cropping sets the visible CropBox boundary of the PDF page — PDF viewers and printers only display the selected region, but the original page content underneath is preserved in the file.
Can I crop specific pages only?
Yes. Choose "Specific pages / range" and enter the page numbers or ranges you want to crop, like 1, 3-5. All other pages will keep their original, uncropped margins.
Is my data safe?
Yes. Cropping happens entirely in your browser using the pdf-lib library — your PDF is never uploaded to a server, so it stays completely private.
What's the difference between the Standard and Wide presets?
Standard Crop trims a modest 5mm from every side, useful for cleaning up small white borders. Wide Crop trims a larger 10mm from every side, better for removing headers, footers, or wider margins.
Does it cost money?
No. The PDF cropper is 100% free to use, with no registration or account required.
