How to use Crop PDF
Crop PDF — complete guide
Cropping is the right fix when a PDF has too much white space or an uneven scanner border around the actual content — common with documents scanned on a flatbed scanner that captures more of the page than intended. Trimming margins tightens the page around the real content.
Because you can set top, bottom, left, and right independently, uneven scans (where one side has a wider border than another) can be corrected precisely rather than cropping all sides equally.
If the document also needs rotating because it was scanned sideways, use Rotate PDF first, then crop afterward. To shrink the resulting file size, follow up with PDF Compressor.
Frequently asked questions
Can I crop each side by a different amount?
Yes. Top, bottom, left, and right can each be trimmed independently.
Does cropping affect PDF quality?
No — the visible page area is adjusted directly in the PDF structure, not re-rendered as an image.
Does this apply the same crop to every page?
Yes, the current tool applies one crop setting across the entire document in one pass.
Is my PDF uploaded anywhere?
No. Cropping happens entirely inside your browser.
Can I undo a crop after downloading?
Cropping modifies the downloaded copy only — keep your original file if you might need the untrimmed version later.
Is this tool free?
Yes, with no sign-up and no limit on how many PDFs you crop.
