How do I remove white margins from a PDF?

Upload your PDF to lnpdf and use the crop tool to trim excess white space around the edges. You can apply the same crop to all pages or adjust each page individually.

Can I crop a PDF to a specific size like A5 or Letter?

Yes. lnpdf allows you to enter exact dimensions or choose from standard paper sizes so you can crop pages to a precise target size.

Does cropping a PDF permanently delete the cropped content?

When you save with lnpdf, the cropped areas are removed from the output file, keeping only the selected region. Your original file is never modified.
