Auto-trim white borders and empty space from PDF pages

PDFCook Remove PDF Margins automatically analyzes the visible content on each page and trims large white borders around scanned or exported documents.

Choose a safer detection mode for faint gray content, normal for typical documents or a stronger trim when light gray areas can be treated as margin. You can also keep 0 to 10 mm of padding around detected content.

Automatic detection works best on light or white page backgrounds. If you want to choose the crop rectangle manually, use Crop PDF.
