Cropping a PDF means redefining the page margins, eliminating excessive white space or isolating a specific section of the content. It is useful for standardising scanned documents with irregular margins, removing fixed headers, or adapting the format for printing.

OnlinePdfEditor shows an interactive preview where you can drag the crop borders on each page. You can apply the crop to all pages at once or customise it page by page.

Cropping modifies the visible boundaries of the page without deleting the underlying content: a useful feature if you want to restore the original margins in the future.

Frequently asked questions

What does cropping a PDF mean?

Cropping a PDF modifies the "crop box" of each page, i.e. the visible area. The removed margins are not visible in the resulting PDF, but the original content is not permanently deleted from the file structure.

Does cropping permanently remove content outside the area?

PDF cropping hides content outside the selected area by modifying the crop box. To permanently remove content (e.g. for privacy) use the redaction tool.

Can I crop all pages with the same measurements?

Yes. You can apply the same crop to all pages in a single operation or set different areas for specific pages.

Are my files uploaded to a server?

No. Cropping happens entirely in the browser via WebAssembly. The file never leaves your device.

Does it work on all browsers?

Yes. It works on Chrome, Safari, Firefox and Edge, both on desktop and mobile.

Is there a file size limit?

In the free version the recommended limit is 50 MB. With the Pro plan you can work with larger files.
