Automatically trim white PDF page margins

WorkCal 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.
