Wide margins are common in scanned documents, exported slides, and PDFs printed from a browser - and they waste space when the page is meant to be read on a small screen.
This tool trims an even margin off every side of every page by the percentage you choose, tightening the content without touching what's inside it.
Cropping happens in your browser, and it only changes the visible page area - nothing is redrawn, resized or compressed.
How to use the Crop PDF
- Select a PDF file.
- Set the margin percentage to trim from each side.
- Download the cropped PDF.
Choosing a margin percentage
A small trim like 5-10% removes excess white border without risking cutting into content; scanned documents with wide borders can often take 15-20% safely.
Common uses
- Tightening margins on a scanned document before printing
- Trimming a PDF exported from a slide deck down to just the slide content
- Preparing a document to display better on a phone screen
Frequently asked questions
Is it free?
Yes, free with no signup.
Does cropping delete content?
No. It changes the visible page boundary; the full original content still exists in the file, just outside the new visible area.
Can I crop each side by a different amount?
Not currently - the same percentage is trimmed from all four sides.
Are my files uploaded?
No. Everything happens locally in your browser.
