Renders behind the QR at adjustable opacity. Auto-forces EC=H so the QR still scans through the photo.
Batch Generation
Upload a CSV to generate up to 500 QR codes in a single batch. Each row becomes its own QR — pick a template or override 21 properties on a per-row basis: colors, frames, dot/eye/eyeball styles, gradients, transparency, size, error correction, format, built-in logo, and more.
21 columns: type, data, filename, frametext, frame, template, fgcolor, bgcolor, size, ec, dotstyle, eyestyle, format, logo, gradient, g2, gtype, gangle, transparent, eyeball, eyecolor. Only type and data are required. Use | to separate fields inside data (e.g. ssid|password|WPA).
All 79 QR types supported, including URL, WiFi, vCard, TOTP, Swiss QR-bill, PIX, PromptPay, ZATCA, PayNow, Bitcoin + Lightning, and more. Download the sample CSV to see every column, all 50 templates, 11 frame styles, and 156 built-in logo icons in action.

Save the entire QR — type, all field values, style, frame, logo, business card design — as a single .qr.json file. Load it later to recreate everything in one click.

What is Aztec Code?
Aztec Code is a 2D matrix barcode standardised as ISO/IEC 24778. It's recognisable by its distinctive bullseye finder pattern at the centre. Aztec was designed specifically for environments where traditional barcodes struggle: low contrast, displayed on a phone screen with anti-aliasing, partially obscured, or printed on textured material. That's why it dominates aviation and rail.
Where Aztec dominates
- Airline boarding passes — the IATA Bar Coded Boarding Pass (BCBP) standard mandates Aztec or PDF417; carriers including Lufthansa, Air France-KLM, Cathay Pacific, ANA, JAL, and most US majors emit Aztec by default.
- Rail tickets — SNCF, Deutsche Bahn, Trenitalia, Renfe, JR East, Amtrak, Eurostar all use Aztec for e-tickets.
- Electronic ID — some national health-insurance cards, library cards, transit passes.
- High-density labels in cramped layouts — warehouse and logistics where space is at a premium.
Why Aztec instead of QR?
- No quiet zone required — Aztec scans even when butted against other content (boarding-pass layouts pack densely).
- Better tolerance for screen rendering — the centre bullseye is highly distinctive even with anti-aliasing.
- Tunable error correction from 5% to 95% — bwip-js defaults to 23%, suitable for screen display.
Limits
Up to 3,067 alphanumeric or 3,832 numeric characters in the largest size (151 × 151 modules). Practical e-ticket payloads are 100–500 characters.
Note on styling
Aztec is not a QR code. QR-only style controls don't apply (centre bullseye is fixed). Foreground/background colours are configurable.
Available in 26 Languages
Fully translated UI, native script rendering, and right-to-left support for Arabic and Urdu.
Frequently Asked Questions
Will iPhone Camera scan Aztec?
Yes since iOS 13 (2019). Earlier iOS required a third-party scanner. Android Camera (Google Lens) has scanned Aztec for years.
Can I encode a boarding pass with this?
Yes, if you already have the IATA-formatted BCBP string from your airline's PSS. The encoder is content-agnostic; paste the string and it produces the Aztec image. Generating the BCBP string itself is airline-specific.
Can I add a logo?
No — the centre bullseye is the finder pattern. Covering it breaks scanning. (Unlike QR, where the centre is data + ECC.)
What error-correction level does this use?
bwip-js defaults to ~23% (the recommended setting for screen-displayed barcodes). For print at high quality you can lower it to free up density; this generator currently uses the default.
Can I generate Aztec in batch?
Yes — use the batch CSV with type=aztec. The data column accepts any text.
Is Aztec patented?
Originally yes (Welch Allyn patents from 1995). All relevant patents have expired; Aztec is now royalty-free and standardised under ISO/IEC 24778.
Does Apple Wallet use Aztec?
Apple Wallet passes can be either Aztec, QR, or PDF417 — the format is set per pass at creation time. Most airline passes default to Aztec.
