Sobre esta ferramenta
Most shipping carriers (UPS, USPS, FedEx, Shopify, eBay, Amazon, DHL, Etsy) generate shipping labels as 8.5×11 inch PDFs by default. The actual label is only 4×6 inches in the corner — the rest is doc tab, return policy, or instructions you don't need.
If you have a thermal printer (Rollo, Zebra ZP450/GK420d, DYMO LabelWriter 4XL, Munbyn, Brother), printing the full 8.5×11 page wastes paper and shrinks the barcode below scannable resolution. This tool extracts the 4×6 label region and outputs a thermal-printer-ready PDF.
The crop is lossless — we rewrite the page boundary, we don't rasterize. Your barcode prints at the original native resolution. Files never leave your browser.

Perguntas frequentes
Does this upload my shipping labels anywhere?
No. The whole tool runs in your browser using pdf-lib (WebAssembly). You can verify in DevTools → Network: zero outbound POST requests when you crop. Your customer addresses never leave your device.
Will the cropped barcode scan correctly?
Yes. The crop is lossless — we rewrite the PDF page boundary, we don't rasterize the page. The barcode prints at the original native resolution.
Which carriers does auto-detect work with?
Top-left auto-detect covers UPS, USPS, FedEx, Shopify, eBay, Amazon, DHL Express, Etsy, ShipStation, Pirate Ship, Stamps.com, and most others. UK/EU carriers like DPD use top-right — switch the quadrant manually.
Does it work with multi-page PDFs?
Yes. Every page in the PDF is cropped to 4×6 in one pass. Useful for batch shipments and merged manifests.
Does it work with A4 (international) labels?
Yes. We read the actual page dimensions from the PDF, so A4 (210×297mm), US Letter (8.5×11), and Legal (8.5×14) all work without any setting changes.
Which thermal printers does the output work with?
All 4-inch thermal printers — Rollo, Zebra (ZP450, GK420d, ZD420, ZT411), DYMO LabelWriter 4XL, Munbyn ITPP941, Brother QL-1100. Output is exactly 4×6 inches at 203 DPI.
Why does Chrome print my cropped label at the wrong size?
Chrome's built-in PDF viewer applies "Fit to Printable Area" by default. Open the cropped PDF in Adobe Reader instead, and pick "Actual size" in the print dialog.
