What cropping changes
Cropping sets the visible area of each page. The content outside is hidden, not rewritten, so text stays sharp and the file hardly changes in size. If you need hidden content to be truly gone, do not rely on cropping.
Good uses
Making a document easier to read on a phone by removing wide margins, trimming the dark edges a scanner leaves, or cutting a repeated header from each page.
Other names for this job
Cropping is what people mean by trim PDF margins, remove white space from a PDF, cut the edges of a PDF, or resize the visible page. Set how much to cut from the top, bottom, left and right, and every page is cropped the same way.

Questions people ask
Is every page cropped the same?
Yes, the same amounts are applied to all pages.
Is the cropped-off part deleted?
It is hidden from view but remains inside the file. Do not use cropping to remove confidential content.
Can I undo it?
Your original file is untouched, so you can always start again.
How do I remove the white margins from a PDF?
Enter the width of the margins in millimetres for each side, check the preview, and press Crop PDF.
Can I crop only one page?
Not here; the same crop is applied to all pages. To crop one page, extract it first, crop it, and merge it back.
Is Crop PDF free? Is there a watermark?
Yes, it is free, and no watermark is added to your file. You can try the tool without an account; a free Bol Ke Likho account is needed to download the result. No payment details are asked for.
Is it safe to use Crop PDF online here?
