Crop PDF — Trim Margins with a Live Preview

Drag the crop sliders while watching a live preview of what stays visible, then apply the same crop to every page or just the ones you pick — great for trimming scan margins or wide whitespace.

Quick answer: Crop PDF

Crop PDF trims margins or whitespace from pages using a live preview — drag the four edge sliders and watch exactly what will stay visible, then apply the crop to every page or just a chosen range. It changes each page's CropBox, which is a display setting, not a content edit.

Input
A PDF and crop amounts for each edge (top/right/bottom/left).
Output
The same PDF with each target page's visible area trimmed.
Know before use
Cropping is not redaction: the trimmed-away area is still stored in the file's MediaBox and can be recovered by resetting the CropBox — never use it to hide sensitive content.
