Why use Crop PDF?

Scanned books carry black borders, exported slides carry unnecessary whitespace, and documents built for US Letter waste space when read on a phone. Cropping tightens the visible page so the content fills the screen. It is the difference between squinting at a column of text surrounded by grey and reading it comfortably.

Privacy and browser processing

Your files are processed in your browser. Nothing is uploaded to a server, so your document never leaves your device.

There is no account to create and nothing to install. Because the work happens on your device, the speed depends on your device rather than on how busy a server is — and closing the tab is all it takes to remove every trace of the file from this page.

Limitations

Worth knowing before you start:

  • Cropping hides content outside the new boundary rather than deleting it from the file — it is not a redaction tool.
  • Password-protected PDFs must be unlocked before they can be cropped.
  • Pages of different sizes may not all suit a single crop rectangle.
  • A crop area cannot be reduced to nothing; a usable minimum page size is enforced.

Frequently asked questions

Is cropping a PDF free?
Yes. Cropping is free, needs no account, and adds no watermark to the file you download.
Are my PDF files uploaded to a server?
No. The crop is calculated and applied in your browser, so the document never leaves your device.
Does cropping actually delete the content outside the crop?
No. Cropping changes the visible page boundary, and the hidden content still exists inside the file. Do not use cropping to hide confidential information — anyone can restore the original view.
Can I apply one crop to the whole document?
Yes. Set the crop once and apply it to every page, which is the usual choice for a scanned book or a set of slides with identical margins.
Can I undo a crop later?
The downloaded file keeps the hidden content, so a crop can be widened again in this tool. Keep your original file if you want to be certain.
Does cropping work on mobile?
Yes. The crop handles are sized for touch, and you can type exact margin values if dragging is fiddly on a small screen.
