Are the marketplace fees automatically updated?
No. Inputs are illustrative and editable. Use the official rate card for your product category, weight, and fulfilment method.
Does the cropper upload customer data?
No. PDF processing runs in this browser. Keep the page open until your download finishes.
Can I crop scanned PDFs?
Image-only pages can be detected when the label and invoice have a clear separator and barcode structure. Unfamiliar scans are flagged instead of guessed. This version does not use OCR or extract SKU data.
Do I need an account?
No account is needed. Calculator inputs can be saved locally on your device.
