What NitroLabel is

NitroLabel is desktop software for designing barcode labels and printing them from imported or live data. Its drag-and-drop designer handles text, barcodes, shapes, and images, with grid snapping, keyboard shortcuts, and undo and redo. Users can map data columns to label variables, preview records, and print batches of unique labels. Imports support Excel, CSV, JSON, XML, and SQLite, including custom SQL queries for SQLite databases. More than 20 barcode types are available, including QR Code, CODE 128, Data Matrix, EAN-13, PDF417, and GS1-128. Printing works through driver-based printers or native ZPL on compatible devices. Live Print checks REST APIs every 3 seconds to 1 minute, then prints new records or queues them for review. NitroLabel runs on Windows, macOS, and Linux, keeps data on the machine, and offers lifetime or yearly licenses.
