What is the Crop PDF?
Cropping a PDF trims the blank or unwanted edges from its pages so the document shows only what you want. Cubestack's Crop PDF lets you drag a crop box on a page preview or type exact margins, then saves a new PDF. Text and graphics are not turned into images, so they stay sharp and selectable. Everything runs in your browser and the file never leaves your device.

Features
Drag to crop
Move the handles on the page preview; the shaded area is what gets cut off.
Exact margins
Type top, bottom, left and right margins in millimetres, points or percent.
All pages or a range
Crop every page, or only pages such as 1-3, 5.
Auto-detect margins
Finds the edge of the content on the page you are viewing and fills in the margins. You can adjust them before saving.
Rotated pages
Margins are measured on the page as you see it, so landscape and rotated pages crop the right edges.
Stays sharp
The page area is changed, not the content, so text and vector graphics are not rasterised.
Popular uses
Scanned pages
Remove dark scanner borders and empty margins.
Slides and printouts
Trim white space so content fills the page.
Reading on a phone or e-reader
Cut wide margins so the text can be shown larger.
Forms and exhibits
Keep only the part of the page you need to share.
Frequently asked questions
Does cropping reduce the file size?
Usually not by much. Cropping hides the trimmed area but the content outside the new edge is still stored in the file. To shrink a PDF, use Compress PDF.
Will the text stay selectable?
Yes. Pages are not converted to images, so text, links and vector graphics are unchanged.
Is my PDF uploaded anywhere?
No. The crop is done in your browser on your own device.
Can I crop different pages differently?
Run the tool once per set of pages: crop one page range, then open the downloaded file and crop another range with different margins.
Why does it say my PDF is password-protected?
Encrypted PDFs cannot be edited. Remove the password first with Unlock PDF, then crop.
