LabelChop

If you sell online, you’ve probably had the cursed workflow: download a shipping label, open Acrobat or Preview, crop the page, fiddle with print scaling, waste a test label, then do it all again tomorrow.

LabelChop is a small desktop app for ecommerce sellers using thermal printers. It watches your Downloads folder, detects shipping label PDFs, crops/resizes them to 4x6 / 100x150mm, and either saves or prints them automatically.

It’s built for the annoying real-world cases: A4 PDFs, Letter PDFs, marketplace exports, carrier labels, international labels, old downloads, and print settings that somehow break right when you need to ship orders.

There’s also a free A4 to 4x6 converter if you just need to fix one label quickly.
