How to crop a PDF

1. Drop the PDF. The first page is drawn in this tab with PDF.js. 2. Drag the frame, or drag a corner. Choose Square or 16:9 if the shape must stay fixed. 3. Leave “Every page” on, or switch to the first page only. 4. Press “Crop PDF” and download.

The frame is a share of the page, not a fixed number of inches. A square frame on a portrait page stays a square share on a landscape page too.

The page gets smaller, the words stay

GustKit sets the page box with pdf-lib. Text inside the frame stays selectable. Text outside the frame is no longer on the page. This is not a photo of the page: use PDF to JPG when you need a picture, then Crop image.

Margins, scans and mixed sizes

Use this to drop a wide scanner margin or to cut a slide deck down to the content. Pages can differ in size. Each one loses the same share of its own width and height. A password-protected PDF has to be unlocked first.

How to check the crop before you send it

1. Open the download and look at the first page and the last page. 2. If a header was cut off, run again with a taller frame. 3. If only the cover needed the trim, choose First page only and keep the rest.

The frame is a share of each page. Mixed page sizes do not share a ruler measurement. Text that stays inside the frame can still be selected. Unlock a password-protected file first.

Frequently asked questions

Can I crop each page to a different area?

Not in one run. The frame is one share, applied to the pages you chose. Crop the first page, download, then crop another area on a second pass if you must.

Will the file get smaller on disk?

The pages get smaller on screen. Pictures that sat outside the frame can still be inside the file. Compress PDF if the download is too heavy to send.

Does a square frame make a square page?

Yes. Square, 4:3 and 16:9 lock the shape of the area you keep. Free lets you drag any rectangle.

Is the PDF uploaded?

No. PDF.js draws the preview and pdf-lib writes the crop in this tab.

Can I type a margin in centimeters?

No. Drag the frame. The preview is the page, so you can see what stays. A fixed margin would hide a different amount on every page size.

The preview is the first page. What about page 3?

Every page loses the same share of its own width and height. Check a later page in the download if the document mixes portrait and landscape.
