How it works
- Choose a PDF file – a preview of the first page appears.
- Enter the margins to remove in millimetres or click “Detect margins automatically”.
- Optionally limit the pages, click “Crop PDF” and download the result.
Notes and limitations
- By default only the visible area (CropBox) is changed: the hidden content stays in the file and could be restored with other software. Choose “Shrink pages permanently” to also change the page size (MediaBox).
- The margins refer to the page as you see it, including rotation.
- Automatic detection looks at the first page; other pages may need different values.
Frequently asked questions
Is the cropped content really deleted?
No – cropping hides the area. If you need to remove sensitive content, do not rely on cropping; use a redaction tool instead.
