Some PDFs have unwanted headers or footers — a printed URL, a timestamp, an old page number style, or a watermark in the margin. Cropping the page edges removes these cleanly without affecting the main content area.
Open the PDF and look at which edge contains the unwanted element: top (header), bottom (footer), left, or right margin. Note approximately how many millimeters or points from the edge it extends.
Go to pdfeditor.onl/crop-pdf. Upload your PDF.
Enter the crop amount for the relevant edge. Start conservatively — crop only as much as needed to remove the element. For a typical footer printed in 8pt text, cropping 15–20mm from the bottom is usually sufficient.
Tip: Use the preview to verify the crop before downloading. If the main content appears to be clipped, reduce the crop margin.
Click Crop & Download. The header or footer region is permanently removed from all pages. The remaining content area is unchanged.
Yes. Cropping reduces the page dimensions by the amount you crop. If the original was A4 and you crop 20mm from the bottom, the result will be A4 minus 20mm height. This is usually fine for screen reading but may affect print layouts.
No. Cropping only removes content from the page edges. A watermark in the center of the page cannot be removed by cropping — it would require an editing or redaction approach.
