Zint Barcode Generator is an open-source solution for generating barcodes, supporting over 50 symbologies, such as Code 128, Data Matrix, QR Code, UPC/EAN, PDF417, Aztec, and GS1 DataBar, among others. Designed to be flexible and accessible, the project includes a graphical interface based on Qt, a command line tool (CLI), and a library with API for integration into proprietary software, making it suitable for both professional users and developers.
It allows encoding data from UTF-8 (Unicode) inputs or raw 8-bit data streams, generating images in formats such as PNG, BMP, GIF, SVG, EPS, and TIFF. Its configuration can be adjusted to meet specific needs, such as customizing dimensions (X-dimension) or creating composite codes.
Licensed under the GPL v3 (with the backend library under BSD-3), Zint is free, lightweight, and supports automation via tools like scripts or integration with existing systems. It is used for tasks such as product labeling, inventory management, and creating QR codes, standing out for its simplicity and broad support for international coding standards.
