About the Crop PDF

Wide margins, scanner borders and stray edges waste space and make a PDF look untidy — especially if you plan to print it or read it on a small screen. Cropping trims those margins to a cleaner, tighter page.

This Crop PDF tool removes the margins around your pages by the amount you choose, right in your browser. The content stays sharp, and because nothing is uploaded, you can tidy confidential documents privately.

How to use the Crop PDF

1. Add your PDF by dragging it in or clicking to browse.
2. Set how much margin to trim from the pages.
3. Click "Crop PDF" to apply it on your device.
4. Download your trimmed PDF.

How the Crop PDF works

This tool works directly with the internal structure of your PDF using established open-source engines (pdf-lib and PDF.js) that implement the ISO 32000 PDF specification. Everything runs locally in your web browser through JavaScript, which means the document is read, modified and re-saved on your own device — it is never transmitted to a server. That is what makes the process both instant and genuinely private.

Because the pages are handled at the object level rather than being re-printed, text stays selectable and sharp and images keep their original quality unless you deliberately choose to compress them.

Tips & best practices

• Trim a modest amount first and check the result — you can always crop a little more, but you cannot easily add margin back.
• Make sure the crop does not clip page numbers or footnotes near the edges.
• To change the page size to a standard format instead of trimming, use the Resize PDF Pages tool.

Standards & accuracy

Built on the PDF (ISO 32000) standard and processed entirely in your browser, so files are never uploaded.

Because processing happens locally, results are consistent and repeatable. For scanned PDFs (images of text with no selectable text layer), text-based operations require OCR first — the tool works with the document's existing text layer.
