How to Crop PDF Margins Online Free — Remove Whitespace

Excessive whitespace around PDF content makes documents look unprofessional and wastes paper when printing. Cropping away those margins gives you a cleaner, more focused document.

Why Crop a PDF?

• Remove scanner borders — Scanned pages often have black edges or excess white space
• Fit content to screen — Eliminate large margins for better on-screen reading
• Save paper — Less whitespace means more content per page when printing
• Professional appearance — Tight margins look cleaner and more polished
