  4. Generate downloads a print-ready PDF sized exactly for your thermal printer

Fix UPS, FedEx, USPS, and Marketplace Labels

Stop wasting thermal labels on bad scaling and rotation. Our tool auto-detects the label area inside an 8.5×11 PDF and converts it to the exact size your 4-inch thermal printer expects.

Auto-detect the Label Area

Our detection algorithm finds shipping labels by looking for common patterns like "SHIP TO", "FROM", tracking numbers, and barcodes. If detection fails, simply drag the crop box over your label.

Fit, Fill, or Scale — Print-Ready Output

Choose how your label content scales inside the 4×6 or 4×8 output:

  • Fit: Scales down to fully fit (no cropping)
  • Fill: Fills the label completely (may crop edges)
  • Actual Size: No scaling, only crops
  • Custom Scale: Fine-tune with a slider (80%–130%)

Frequently Asked Questions

Thermal printers expect labels in a specific orientation. Our tool automatically detects the best orientation and rotates the output to match your printer's requirements. You can also manually force portrait or landscape, or use the quick rotate buttons.

Yes! For PDF inputs, we preserve vector content when possible, which keeps barcodes crisp and scannable. For image inputs, we render at high resolution to ensure barcodes remain readable.
