Crop PDF Margins
Trim wide white margins so the content fills more of the page.
About this converter
Academic papers and older scans often carry margins wide enough to waste half the page. That matters on a tablet or an e-reader, where the text ends up tiny because the screen is filled mostly with white.
Trimming the margins makes the content fill more of the page, so it reads larger without zooming and panning around. Each edge is set on its own, because margins are rarely even — a book scan has a wide gutter down one side, and headers and footers take different amounts off the top and bottom.
Nothing is deleted. A PDF records the visible area separately from the content, so this only changes what is shown — the trimmed edges are still in the file, and the crop can be undone.
Frequently asked questions
Will it cut off my text?
Only if you trim more than the margin actually is. Start low on any edge you are unsure of and increase it if there is still white space to spare — nothing is destroyed, so you can try again on the original.
Is anything lost?
No. A PDF stores the visible area separately from the page content, so cropping hides the edges rather than deleting them.
Do my PDFs get sent anywhere?
No. Everything happens on your own device, so your documents never leave it. That matters more than usual for PDFs, which tend to be contracts, statements and scans.
Does it work with password-protected files?
Not yet. A protected PDF has to be unlocked with its password first.
