Crop PDF

Crop a PDF online for free without uploading a single file. Just open your PDF, drag a crop rectangle over the first page to mark the area you want to keep, and apply that crop box to every page to trim wide margins or unwanted whitespace. This PDF crop tool renders your document with pdf.js and rewrites the crop box with pdf-lib entirely in your browser, so nothing is ever sent to a server. Cropping is lossless — the original content stays in the file, only the visible area changes — and you download a clean cropped PDF in one click.

🔒 100% private — files never leave your device

Frequently asked questions

Does the crop apply to every page?

Yes. The rectangle you draw on page one defines a single crop box that is applied to all pages, and it is clamped to each page's own size so it never overflows.

Is my PDF uploaded to a server?

No. The PDF is rendered and cropped 100% in your browser. Your file is processed locally on your device and is never uploaded, so cropping stays completely private.

Does cropping delete the content outside the box?

No. Cropping sets the visible crop box, so the content outside the rectangle is hidden but preserved. The change is lossless and no page data is removed.

What file types can I crop?

This tool crops PDF files only. You load one PDF at a time, mark the crop area on page 1, and download the result as a cropped PDF.

Can I crop each page differently?

No. You draw one crop rectangle on the first page and it is applied to every page. It works best for documents where all pages share the same layout and margins.

Is there a file size limit?

There is no fixed limit — the PDF is processed in your browser, so it depends on your device's memory. Very large PDFs may render more slowly, but nothing is uploaded.
