How to Convert Amazon Shipping Labels to 4×6 Thermal

Amazon Buy Shipping and many marketplace labels arrive as letter-size PDFs. Your 4×6 thermal printer needs a PDF that matches the label dimensions exactly.

Quick steps

  1. Download your Amazon shipping label PDF.
  2. Open Thermal Label Fixer and upload the file.
  3. Let auto-detect find the label area, or adjust the crop box.
  4. Choose 4×6 (or 4×8) preset and click Generate PDF.
  5. Print at 100% scale — no “fit to page.”

Common mistakes

  • Printing letter PDFs with “Fit to page” — shrinks the barcode.
  • Screenshotting labels — loses quality and breaks barcodes.
  • Wrong rotation — use “My label is sideways” if needed.
