Crop Shipping Labels to Standard 4×6" Thermal Format
Convert 8.5×11" PDF shipping labels from USPS, eBay, Etsy, PayPal, Amazon, and Pirate Ship into crisp 4×6 thermal labels ready for Rollo, Munbyn, or Zebra printers. 100% free, vector barcode preservation, and zero server uploads.
100% Client-Side Privacy
All label rendering and cropping executes locally inside your web browser. Your PDFs, customer names, addresses, and tracking numbers are never uploaded to any cloud server.
Pure Vector Barcodes
Unlike raster screenshot tools that blur barcodes, ThermalCrop preserves native vector line art so tracking numbers and QR codes scan instantly on carrier laser scanners.
Universal Thermal Compatibility
Outputs standard 288×432 pt (4×6 inch) PDF documents engineered to print cleanly on Rollo, Munbyn, Zebra, Brother, DYMO, Jadens, and Phomemo thermal printers.
How to Crop Shipping Labels to 4x6 Thermal Format
- Upload or Drop Your PDF: Select your 8.5×11" shipping label file from USPS Click-N-Ship, eBay, Etsy, or PayPal.
- Adjust Bounding Crop: ThermalCrop automatically detects the label boundaries. You can toggle portrait/landscape orientation and choose safe insets (0 pt, 10 pt, or 14 pt) to avoid printer edge-clipping.
- Export and Print: Click "Download 4x6 PDF" or "Print". In your printer dialog, select 4×6" paper size and 100% actual size.
