Barcode Mint

Barcode Mint is a free online barcode and QR code generator that produces production-ready codes in seconds — no signup and no watermark. Choose from 100+ symbologies, including QR, Data Matrix, PDF417, Aztec, Micro QR, Code 128, Code 39, EAN-13, UPC-A, MaxiCode, DotCode, and the full GS1 family (GS1 QR, GS1 Digital Link, GS1 Data Matrix), then fine-tune bar width, height, colors, margins, and error correction level (L/M/Q/H) with a live preview before you export.

Built for online sellers, warehouses, restaurants, and marketers, Barcode Mint exports crisp PNG and SVG files and generates codes in bulk from a CSV — ideal for product labels, inventory tags, menu QR codes, event tickets, WiFi-sharing cards, and full print runs. Every code is encoded with a reference-grade engine (BWIPP), with built-in Reed-Solomon error correction on QR codes, so GS1, retail, and postal barcodes scan reliably the first time, even with a logo overlay or minor print damage.

Different formats suit different jobs: QR codes read natively on virtually any smartphone camera, making them the default for menus, packaging, and marketing; Data Matrix packs the same data into a smaller footprint for tight industrial part-marking; Aztec drops the quiet-zone requirement, which suits dense mobile tickets; PDF417 stores far more data per code, the format airlines and ID cards rely on.

Developers can add barcode and QR generation to any app with the Barcode Mint REST API — one request returns a PNG or SVG image, with commercial licensing included and volume tiers from 500 to 50,000 requests per month. Start free in the browser with unlimited PNG/SVG exports, and upgrade only when you need bulk CSV batches, vector (PDF/EPS) export, or the API at scale.
