Common Mistakes

  • Editing the only copy
  • Cropping all pages when only one page needs it
  • Assuming hidden content is permanently removed

Use Save As or export settings that preserve crop boxes.

Undo and leave more margin before applying.

Use a redaction or optimization tool if permanent removal is needed.

Pages have different sizes

Apply crop settings page by page or normalize page sizes.
