Batch Convert Labels to 4×6 Thermal

Shipped 50 orders and every label PDF is letter-size? Fix them all at once instead of one file at a time.

Quick steps

  1. Collect your label PDFs (or zip them into one archive).
  2. Open Batch Thermal Label Fixer.
  3. Upload files or a ZIP — preview the crop on each label.
  4. Choose fit mode and 4×6 or 4×8 output.
  5. Download the ZIP of print-ready thermal PDFs.

When to use batch vs single

  • Batch Thermal Fixer — many PDFs after a shipping session; all processing stays local.
  • Thermal Label Fixer — one label at a time with fine-tuned crop controls.
