Crop a PDF

Drag the box, or let us find the edges

Drag the corners or edges of the box over the page, with your mouse or your finger, or drag inside it to move it. Prefer exact numbers? Type the Margins in mm instead.

Tap Trim white margins and we look at the page, find where the text and pictures start and end, and crop to that with a thin white edge left around it. With All pages, we look at every page and keep a box that cuts nothing off any of them. It works best on PDFs made on a computer. On a scan, specks of dust near the edge count as content, so check the box before you crop.

All pages or just one

All pages crops every page by the same margins. This page only gives each page its own box: crop page 1, go to page 2 with the arrows and crop it differently. Pages you leave alone are not changed. Pages that are turned sideways are cropped the way you see them on screen. If a page is the wrong way round, rotate it first.

No loss of quality

Cropping only changes the visible area of each page. Nothing is turned into a picture, so text stays sharp, selectable and searchable, and the file stays about the same size. Form fields and bookmarks are kept. Cropping does not make a file smaller; to do that, use Compress PDF.

Shipping labels

If your shipping label sits on a bigger page, choose the 4 × 6 label shape and place the box over the label. The box keeps the 4 × 6 inch shape, so the cropped page fills a 4 × 6 label when your print settings scale it to fit. We have not tested this on a label printer, so print one test label first.

What we tested

On 29 October 2026 we ran this page in Chromium (automated tests, on a computer screen and a phone-sized screen with touch) with two public IRS forms. Trim white margins on all pages took under half a second for each. The 6-page W-9 went from 138 KB to 131 KB, and the 2-page Form 1040 from 215 KB to 217 KB. Every page was cropped, all 23 and 199 form fields were kept, and the text we read back from both files was the same as before. Pages turned sideways were cropped the way they are shown.

What cropping does not do

Cropping hides everything outside the box, but it is still inside the file. Someone with the right PDF software can bring it back or copy its text out. To remove private details for good, use Redact PDF. To remove whole pages, use Delete pages.
