Crop PDF cuts away the edges of your pages. Draw a rectangle on the preview of page 1 to mark the area to keep, or type the margins to remove from the top, bottom, left and right in millimetres. The new page size is shown as you go, and the crop can be applied to every page or only to the pages you list.
Typical uses are trimming wide white margins so slides or e-books are easier to read on a phone or e-reader, removing printer marks, or cutting a scanned page down to the receipt in the middle. Cropping is lossless and runs in your browser – the PDF is never uploaded.
How to use the Crop PDF tool
- Choose or drop the PDF you want to crop.
- Drag on the page preview to draw the area to keep, or enter the four margins in millimetres.
- Use the presets or Same value for all sides for even margins, and enter page numbers to crop only some pages.
- Click Crop PDF to download the cropped file.

How PDF cropping works
A PDF page has boxes that tell viewers and printers which part of the page to show. This tool sets those boxes (the media box and crop box) to the area you choose, so the outside is hidden and the page is smaller. Nothing is re-drawn, so text stays selectable and quality is identical.
Because the hidden content is technically still in the file, cropping is not a safe way to remove sensitive information. To get rid of whole pages use Remove pages; for images, Crop Image removes pixels for real.
Cropping documents with different page sizes
Margins are measured from each page’s own edges, so the same 10 mm crop works on A4 and Letter pages alike. If some pages are much smaller than the margins you entered, they are left unchanged and the tool tells you how many were skipped.
Frequently asked questions
How do I remove white margins from a PDF?
Load the PDF and drag a rectangle around the content on the preview, or enter the margin sizes. Then click Crop PDF.
Can I crop only one page?
Yes. Type its number in the Pages field before cropping; other pages keep their size.
Does cropping reduce the file size?
Usually not, because the cropped-away content is hidden rather than deleted. Use Compress PDF if you need a smaller file.
Is the PDF uploaded?
No. The crop is applied in your browser and the file never leaves your device.
