Frequently asked questions
Is this tool free?
+
Yes, completely free with no limits. No account required.
Is my PDF uploaded to a server?
+
No. Cropping happens entirely in your browser using pdf-lib. Your file never leaves your device.
Does the crop apply to every page?
+
Yes. The margins you set apply uniformly to all pages, so page numbers and layout stay aligned throughout the document.
Does cropping delete content?
+
No. Cropping adjusts each page's visible CropBox — the underlying content isn't deleted, just clipped from view. This matches how PDF viewers and printers treat the page.
Can I undo a crop?
+
The tool doesn't modify your original file — it downloads a new, cropped copy. Keep your original if you might need the full page again.
