Crop PDF
Scanners love leaving black edges, and downloaded forms often carry wide blank margins. Cropping fixes both in seconds. Enter how much to trim from each edge as a percentage — for example 5% from the top — and every page gets a tighter frame. Because cropping works through the PDF crop box rather than re-rendering pages, no content quality is lost and file size stays the same: the trimmed areas are simply hidden from view. Adjust the margins, click Crop PDF, and download the cleaned document. Everything runs locally in your device’s browser, so confidential layouts never leave your machine.
Guide: How to Edit a PDF — step-by-step walkthroughHow to use Crop PDF
Add your PDF
Click the file picker and select the document whose edges you want to trim.
Set the margins
Enter a percentage to cut from the top, right, bottom, and left — only the fields you need.
Crop and download
Click Crop PDF and save the document with its new, tighter page frame.
Tips for best results
- Start with 5% on each side and increase only if black edges remain.
- Cropping hides content via the PDF crop box — nothing is permanently deleted.
- Extract a few pages first with Extract Pages if only part of the document needs a different crop.
Frequently asked questions
Does cropping permanently delete the content underneath?
No. Cropping sets the page’s crop box, which controls what viewers display. The hidden content remains in the file, so quality and layout are fully preserved — the file simply shows a tighter frame.
Can I crop different pages by different amounts?
Not in one pass — the same margins apply to every page. To crop a subset differently, extract those pages with Extract Pages, crop each part, then merge the results back together.
