How to Crop PDF Pages to Remove White Margins
Updated 2026-02-18Verified Private
Cropping a PDF isn't about resizing—it's about removing the parts of the page you don't need, like old headers or wide margins.
Why is this needed?
Better for mobile reading! Trim wide margins so the text appears larger on small screens.
!Step-by-Step Instructions
1
Upload PDF
Upload your document to the [Crop Tool](/tools/pdf-crop).
2
Select Crop Area
Use your mouse to draw a box around the area you want to KEEP.
3
Apply and Download
Tulz will trim all selected pages to match your new boundaries.
Pro Tips
- •Use 'Auto-Crop' to automatically detect and remove empty white space.
- •Be careful not to crop too close to text; remember to leave a small 'breathing' margin.
Frequently Asked Questions
Can I crop different pages differently?
Yes, you can set a global crop or adjust individual pages.
