eBay's "print shipping label" PDF is a full 8.5 x 11 page with the label turned sideways in one corner. On a 4x6 thermal printer (Rollo, Zebra, MUNBYN, Phomemo and others) it comes out sideways and shrunk. This tool turns it into a proper upright 4x6 PDF.
Shown with a made-up demo label. The label is moved, not resized, so barcodes stay exactly as eBay generated them.
What it does
Automatic: download your label from eBay as usual and an upright eBay_label_..._4x6.pdf appears next to it. You can close the eBay tab at any time.
Batch: drop several labels at once and get one combined multi-page 4x6 PDF to print in one go.
Private: labels contain your buyers' names and addresses, so everything happens on your computer. Nothing is uploaded, there is no account and no tracking.
Checksums and release notes are on the latest release. Every download is built from the public source by GitHub Actions and tested on Windows, macOS and Linux first.
Printing
Print the result at Actual size / 100%, not "Fit to page", on 4x6 label stock. The PDF is already exactly 4 x 6 inches.
