Crop PDF questions
Everything you need to know about visually cropping PDF pages online.
PDF cropping sets a crop box that hides the areas outside the selected region. The underlying content outside the crop area is masked, not deleted. A PDF reader that ignores crop boxes could still display the full page. To permanently remove content, the PDF would need to be re-rendered.
The selection is drawn on page 1 and the same crop box (in PDF points) is applied to every page in the document. This works best for consistently-sized pages such as A4 or Letter documents. For mixed-size documents, the crop is applied as absolute coordinates which may not align perfectly on differently-sized pages.
No. The preview is rendered entirely in your browser using PDF.js — your file is not sent to our servers until you click the Crop PDF button. This means your document stays private until you explicitly choose to process it.
Yes. All files are transferred over 256-bit SSL and stored in encrypted cloud storage tied to your anonymous session. No one else can access your files, and they are permanently deleted after 2 hours. We never read or share your documents.
