FAQ

Frequently asked questions

How the calculation works and where its limits are.

How do I crop margins on a PDF online?

Upload your PDF file, use the margin sliders or percentage inputs to set top, bottom, left, and right trim boundaries with live visual preview, choose whether to apply to all pages or just the current page, and click 'Crop PDF'.

Does cropping a PDF reduce its file size?

Cropping adjusts the visible display boundary (MediaBox and CropBox) of the PDF. To reduce file size while cropping, you can also run the cropped file through our Compress PDF tool.

Is cropping performed securely without uploading my document?

Yes. All PDF boundary calculations and vector adjustments execute locally inside your browser memory.
