How cropping a PDF works
Every PDF page has a crop box: the rectangle of the page that viewers show and printers print. Cropping here moves that rectangle in to the area you drew. It is the same thing Acrobat’s crop tool does, and it is lossless — nothing on the page is redrawn or re-compressed, so text stays sharp and selectable and images keep their full resolution.
Cropping hides; it does not delete
Because only the visible boundary changes, whatever lies outside it is still in the file. That is what makes a crop reversible, and it is also why cropping is the wrong tool for hiding an account number or a signature before sharing: anyone with a PDF editor can widen the crop box again. For that, the content itself has to be redacted.
One crop, many page sizes
The box you draw is kept as a share of the page rather than as a fixed size. Applied to every page, each one loses the same proportion from each edge, so a document that mixes A4 and Letter, or portrait and landscape, is trimmed consistently instead of having a fixed rectangle land in the wrong place on half its pages. The margin boxes show the trim in millimetres on the page you are looking at; switch the page shown to check any other.
Rotated and already-cropped pages
A PDF page can be stored one way and displayed another — scanners and phones often save landscape pages as sideways portrait pages with a rotation flag — and a page cropped once before shows only part of its full sheet. The crop you draw is worked out on the page exactly as it is displayed, then translated into the page’s own coordinates, so it always lands on the area you saw under the box.
Frequently asked questions
Is my PDF uploaded to crop it?
No. The page preview is drawn in your browser tab, the crop is applied there, and the cropped file is handed straight back as a download. Nothing is sent to a server.
How do I crop a PDF?
Open the file, then drag on the page preview to draw the area you want to keep. Drag the box to move it, or its edges and corners to resize it; the margin boxes beside it set each edge exactly, in millimetres. Choose whether the crop applies to every page or only some, and save.
Does cropping delete the part of the page that is cut off?
No — and this matters if you are cropping to hide something. Cropping sets the visible area of the page, the same way Acrobat’s crop tool does; the content outside it stays in the file and can be revealed again with any PDF editor. To remove information for good, it has to be redacted, not cropped.
Can I crop all pages at once?
Yes, and that is the default. The same crop is applied to each page in proportion to its size, so on a document mixing A4 and Letter pages each page loses the same share of each edge. Choose “This page only” or type page numbers to crop just some pages.
Does cropping reduce the quality of the PDF?
No. Nothing is re-rendered or re-compressed: text stays sharp and selectable, and images keep their original resolution. Only the page’s visible boundary changes, which is also why the file size hardly changes.
Does it work on rotated or landscape pages?
Yes. You draw the crop on the page the way it is displayed, and it is applied to that same area however the page is stored — including scanned landscape pages saved as sideways portrait pages, and pages that were cropped before.
