How to Crop a PDF

Three steps, all in your browser.

1

Add your PDF

Drag in a PDF or click to browse. The first page appears with a crop box on top.

2

Frame the keep-area

Drag the box to move it, or pull a corner to resize. Choose whether to crop just the first page or every page.

3

Crop and download

Click Crop PDF to download a new file trimmed to your box. Sizes stay proportional even if pages differ.

Cropping hides margins without deleting anything. To remove whole pages use Delete Pages, to turn them upright use Rotate PDF, and to shrink the file use Compress PDF.

What cropping changes

Cropping sets the page boxes rather than deleting anything, which is why the result can be undone and why the file rarely gets smaller.

Frequently Asked Questions

How do I crop a PDF?
Load your PDF, then drag the crop box over the first page so it frames the area you want to keep. Pull any corner to resize it. Choose “all pages” or “first page only”, then click Crop PDF to download the trimmed file.
Does cropping delete the content outside the box?
Cropping does not delete that content: the tool sets the PDF’s crop and media boxes to your rectangle, so viewers show only that area and it prints that way. The bytes outside aren’t re-rendered away, but the visible, printable page becomes your cropped region. If you need the hidden content gone for good, print the cropped file to a fresh PDF.
Can I crop every page the same way?
Yes — one crop box can cover every page. Pick “All pages” and the box is applied to each page proportionally, so pages of different sizes crop to the same relative area. Choose the other option to crop the first page only.
Is my PDF uploaded anywhere?
No — the PDF stays on your device. The page is rendered locally with the same engine Firefox uses for PDFs, and the crop is applied in your browser with pdf-lib. Nothing is uploaded — closing the tab clears everything.
