Tips for Cropping PDFs
- Check another page: choose it under Preview page to make sure the crop fits every page.
- Cropping hides, it doesn't delete: the area outside the box is no longer shown or printed, but to remove private text for good use the redaction (whiteout) in our PDF Editor.
- Pages also sideways? Fix them first with Rotate PDF.
