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.

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?
It 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.
Can I crop every page the same way?
Yes. Pick “All pages” and the box is applied to each page proportionally, so pages of different sizes crop to the same relative area.
Is my PDF uploaded anywhere?
No. 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.
