Scanned or exported PDFs often have needlessly wide margins: a skewed scan, an oversized paper format, or empty space around a slide. This tool provides a real editor for that: your page appears as a preview, with a draggable frame on top that you resize directly at the corners.

Drag the frame at the four corner handles or move it as a whole until only the area you want stays visible. The millimetre values for top, right, bottom and left are calculated automatically from your selection and can also be entered directly if needed. The crop applies to all pages equally.

Everything runs locally in the browser via pdf-lib. Because only the CropBox is set, the cut is lossless and reversible at any time - the trimmed area is hidden, not deleted. Honestly framed: content in the trimmed area remains in the file (only hidden) - to truly remove content, use "Redact PDF".

FAQ

Yes, the dragged frame is applied equally to every page.

Can I crop visually with the mouse?

Yes, drag the frame right on the page preview to the corners you want.

Is the PDF uploaded?
