About Crop PDF

Crop PDF pages to get rid of wide white margins before reading on a phone or tablet, or to cut a slide, a chart or a receipt out of a larger page. When the text sits differently on each page, set Crop to Each page’s own white margins: every page is trimmed to its own content and keeps the Margin to keep you choose, 5 mm unless you change it. The margin color is read from the page edge, so grey scans are trimmed too, and the black border a scanner lid leaves is cut away.

To keep one exact area, leave Crop on To the box I draw, drag on the preview and fine-tune the corners, or press Trim white margins to fit the box to the content of the page shown. That box is used on every page, so flip through with the arrows to check it fits, or list only some pages in Pages, for example 2-5. When the chart or photo is a picture stored inside the PDF, Extract Images from PDF saves it in its original quality. Keep in mind that cropping hides what's outside without erasing it from the file. To remove sensitive content for real, use Redact PDF.

Why use Cubfile for this

  • Each page trimmed on its own

    Every page gets a crop around its own content, with 0 to 30 mm of margin left around it.

  • Made for scans

    The margin color is read from the page edge, so grey scans are trimmed and black scanner borders removed.

  • Draw what to keep

    A resizable box over a live preview, with the kept share of the page shown as a percentage.

  • Content stays sharp

    Cropping changes the visible area only, so text and graphics inside it remain vector.

FAQ

Crop PDF: questions and answers

How do I crop PDF margins?
Choose Each page’s own white margins and click Crop PDF. Every page is trimmed to its own content with the margin you set, and it works on scanned pages too. To use one box for all pages instead, press Trim white margins or drag a box yourself, then check a few pages before cropping.
Can I crop PDF pages to different sizes?
Yes. Each page’s own white margins gives every page its own crop, so pages whose text sits differently all end up with the same margin around their content. A box you draw applies to every page in the task; to use different boxes for different parts, run the tool again with another range in Pages.
Is the cropped-off content deleted?
No. Cropping hides it, and some editors can bring it back. Use Redact PDF when content must be removed permanently.
Can I crop large PDFs for free?
Free accounts can crop files up to 50 MB twice a day, and visitors get 2 tasks in total. VIP handles files up to 1 GB without a daily limit.
Who can see the pages I crop?
Nobody but you. The preview is drawn in your browser, and the copy sent to our server for cropping is deleted automatically after an hour.
