Barcode & QR Code Generator

A free online utility tool that generate barcodes in Code128, EAN-13, Code39 formats and QR codes. Simple, fast, and completely private — just open and use. Generating barcodes is essential for retail product labeling, inventory management, shipping labels, event ticketing, and library cataloging. Creating Code128, EAN-13, or Code39 barcodes typically requires dedicated software or paid SaaS subscriptions, yet the encoding logic is straightforward enough to run entirely in a browser with no installation. Supports four formats — Code128 (universal), EAN-13 (retail products), Code39 (industrial), and QR Code (URLs and text) — with adjustable module size, margin, and output as PNG or SVG. QR codes can encode up to 2,953 bytes. Enter your data (text, URL, or number), choose a barcode format (Code128, EAN-13, Code39, or QR Code), adjust size if needed, and click Generate. Download the image as PNG or SVG. All generation happens locally in your browser. Your data is never uploaded — safe for creating barcodes for internal product codes or private links.
