Barcode Generator

This tool converts input data into machine-readable barcodes across common linear symbologies. It is designed for developers, labeling technicians, warehouse staff, and e-commerce sellers who need standards-compliant codes for inventory, packaging, and product tagging. Output is vector-friendly and suitable for high-resolution print pipelines.

Conceptually, the engine applies per-symbology encoding rules, validates input, computes check digits when required, and produces a scannable symbol. For Code128, the data is encoded using subcodes; for EAN-13, a 12-digit payload plus a check digit; for ITF or Code39, character mappings are applied. The engine outputs SVG for scalable printing or PNG for quick previews.

Key users benefit from a single interface that supports multiple symbologies, precise size and margin configuration, and optional human-readable text. The tool emphasizes accuracy, reproducibility, and easy integration into labeling workflows or software tests. It helps reduce labeling errors and accelerates barcode-ready asset creation.

Core features include input validation, type selection, encoding per symbology, check-digit handling, quiet zone configuration, and export options. Typical use cases include UPC/EAN labeling for retail, Code128 identifiers for SKU streams, and ITF labels for pallets. This tool is suitable for developers and operations teams building barcode-driven processes without external services.
