What Is a PDF Crop Box?
Every PDF page has a crop box that defines the visible area. By adjusting the crop box coordinates, you effectively trim the page without losing any content. Our tool modifies these coordinates based on your entered margins, giving you a perfectly cropped PDF.
Tip: Always keep a backup of your original PDF before cropping. If you need to undo the changes, just re‑upload the original file.
