What is Crop PDF?
Cropping a PDF removes unwanted content at the page edges - scanner borders, oversized white margins, visible paper edges in a scanned document, or fixed header and footer strips. This PDF cropper uses an interactive canvas where you drag 8 resize handles on a live page preview to define exactly what to keep. A dark overlay masks everything outside the crop area so you see the precise result before downloading.
For pixel-accurate work, type exact values for each edge - top, right, bottom, left - directly into the margin input fields. The crop rectangle on the preview syncs with your inputs in real time. This makes it straightforward to remove a consistent border width from every page of a scanned document or trim a fixed header height that appears uniformly across all pages.
Apply the same crop to all pages in one click, or switch to per-page mode to navigate page by page and set different crop dimensions for pages with varying layouts. Both modes are available without switching tools.
The output uses standard PDF CropBox and MediaBox values - the correct way to define page boundaries in the PDF specification. Cropped documents open correctly in Adobe Acrobat, Apple Preview, Chrome, Edge, and any standard PDF viewer or printer without compatibility issues.
All processing runs locally in your browser. No file is uploaded to any server, making this safe for confidential contracts, scanned medical forms, legal filings, and sensitive financial documents that should not leave your device.
