FBA label resize FAQ
Does this change the FBA label content?
No. It adjusts the PDF page size and placement. It does not rewrite barcode or text content.
Which processing mode should I use?
If the label has blank space at the bottom, Crop bottom blank area is often useful. If no content can be lost, use Fit full content and check the preview.
