About Crop PDF

Crop PDF Online — Fast, Secure & Private

Excessive white margins, misaligned scanner borders, and uneven page sizes can make PDF documents awkward to read on mobile devices, e-readers, and tablets. Our Crop PDF tool allows you to visually trim margins or focus on specific content areas across your entire document. Simply drag the crop handles on the interactive preview, and our client-side engine standardizes your page dimensions instantly without compromising document quality.

What is Crop PDF?

PDF cropping recalculates the `/CropBox` and `/MediaBox` coordinate boundaries within the PDF page dictionary. The engine updates the viewport dimensions to display only the selected rectangular area, effectively clipping away unwanted border margins while preserving the underlying vector text and graphics intact.
