What This Tool Does
Crop PDF trims the margins of a PDF so only the region you want remains visible, then gives you back a new file — without anything leaving your browser. Drop a PDF, drag the crop box over the page, and download the result.
The box you draw is stored as proportions of the page rather than fixed measurements, so a single crop applies cleanly to every page even when page sizes differ.
Tip:Cropping hides content by setting the page's crop box — it is reversible and never re-renders the page, so there is no quality loss.
Drag to Crop, Check Every Page
Drag the box or any of its handles to set the crop, or type exact margins in the four inputs. If your document has more than one page, step through it with the navigator to confirm the same crop looks right everywhere before you apply.
Rotated Pages Are Handled Correctly
If a page displays rotated, the crop is still measured in the orientation you see and mapped to the page's true coordinates, so what you box on screen is what gets cropped.
Nothing You Drop In Ever Leaves Your Device
The preview is rendered in your browser and the crop is applied by a WebAssembly module loaded into the same tab. Your PDF is read, previewed, and rebuilt on your device with no upload step.
No. Cropping sets each page's crop box, which tells readers how much of the page to show. The content outside the box is hidden, not erased, so the crop is reversible and the underlying page is never re-rendered or recompressed.
Does the crop apply to every page?
Yes. The box you draw is stored as proportions of the page, so it applies to all pages even when they have different sizes. Use the page navigator to preview how the same crop lands on other pages before you download.
Will the crop still look right on a rotated page?
Yes. The crop is worked out in the orientation you see on screen and translated to the page's real coordinates, so a page that displays rotated is cropped exactly where you drew the box.
Is my PDF uploaded anywhere?
No. The page preview is rendered locally in your browser and the crop is applied by a WebAssembly module loaded into the same tab. Your file is read and rebuilt entirely on your device — it is never sent to a server.
