Drop the label PDFs you download from Seller Hub. Each order page is cut at Flipkart's dashed line into a shipping label and a tax invoice, and you get two PDFs back.
Labels PDF: the courier label above the cut line, cropped to its border (about 7.8 × 12.7 cm). Print at actual size.
Invoices PDF: the GST tax invoice below the cut line.
One page per order. Several files or multi-order PDFs are combined in upload order.
Pages are only cropped, never redrawn, so barcodes and QR codes stay scannable.
Labels 0 pages
Invoices 0 pages
Everything happens in your browser. The PDFs, which contain buyer names and addresses, are never uploaded anywhere.
